I drink three cups of coffee a day, first thing in the morning. If there is caffeine in something else I consume I am ignorant of it.
Ideal amount, 3-5/day
That is what i understand as well.
400 Mg? sounds orders of magnitude beyond lethal. How do you even shove all that into your system?
I think it's a joke about Mg vs mg.
Exactly. Capital letters matter in science and technology.
Oh, ok so that was only a 10⁹ times more... No biggie. LOL.
Anyway, as long as you're able to sleep well, it should be ok. Personally, I think 2 cups (2*200 ml) is a good amount for me. The exact amount of caffeine that contains depends on the type of coffee beans I use. The concentration in the drinkable liquid should be around 300 mg/l, but who knows really. Dark roast will have less than light roast. In any case, that could be something like 2cups/d *0.2 l/cup *300 mg/l = 120 mg/d. Compared to that, I would still say your caffeine intake is a lot higher than mine.
Anyway, as a fun thought experiment, I looked up what caffeine costs and what it would take to buy 400 Mg of it. Sigma-Aldrich/Merck sells 25 kg drums of this stuff and they charge only 1060 € for each. What a bargain for food grade caffeine!
That means, you would need to order 16 000 drums of it. That will be quite a few pallets. Is that going to be more than a single lorry? Don't worry about it. It will cost you only 16 960 000 €, so I guess now would be a good time to start a company to get those tax deductions on chemical orders. On the other hand, you might actually want to contact one of the many factories that produce decaf beans and ask for a better price. All of that caffeine has to go somewhere, right?
Usually, I would recommend using gloves, respirator, full hazmat suit etc. when handling this kind of cargo, but in this case that would kinda defeat the purpose.

Zero.
There are too few of us.
Also zero, for like 20 years now.
Maybe the occasional sip of coffee if I have a headache

Hahaha
Found the mormans.
I don't know man, I can't really think of many drugs I haven't done in some form or another. I just don't use stimulants anymore, as I've already enough problems being overstimulated.
I drink to make other people more interesting.

Edit Also how do you know we aren't morwomans instead of mormans?
I like to boof a pot of coffee in the morning.
The silent majority has been real silent in this thread — but thank you for speaking up for proper technique.
I somewhat recently found out my SO thought boofing was just chugging. The revelation and explanation changed the meaning of a decade of jokes in an instant.
TIL
It's not just chugging, it's butt-chugging
Completely random amounts of black coffee and espresso, ranging from an entire pot or 4+ shots of espresso a day to months without bothering.
Between this and your name, you are my kind of people loll
None anymore. It took me a while to realize the the most energetic and level headed people that I know in my life don't even consume caffeine.
Caffeine addition keeps you permanently tired and getting the next hit just brings you back up closer to to the energy levels of people who don't consume it.
It is hard as hell to quit because it is so addictive, but the other side is so much better..
I go through periods of high and low caffeine intake, so I have some experience in managing withdrawals.
Let's say you want to go down from 4 cups to 2 cups. Here's how to do it:
- Write down how much you currently use. Let's say you're using the traditional 60 g/l recipe and a 200 ml cup. Therefore your starting point is: 60 g/l × 0.2 l × 4 cups/d = 48 g/d
- Prepare a daily plan on how do you go from 48 g/d (4 cups/d) to 24 g/d (2 cups/d). I would recommending reducing the does by 1 g of beans per day. So, if you used 48 g of beans yesterday, grind only 47 g today and 46 tomorrow etc. If headaches occur, you need to go slower. If you're drinking dark roast or if you have a headache resistant head, you can probably get away with 1.5 g/d or 2 g/d reduction rate.
- Don't switch to another type of coffee while ramping down your intake, since the different caffeine concentration in the beans will change the daily dose. You don't know the mass of caffeine, but you do know the mass of the beans you grind. Don't introduce unknown variables. This is hard enough as it is.
- Don't drink coffee made by other people. You won't be able to control your intake properly.
That's how I do it when ramping down my intake. You can also go all the way to zero if you like. The same logic applies to tea as well, but doing it gets a bit tricky. The concentration of caffeine in the solids is much higher in tea, so 1 g/d reduction rate is far too rapid. You also need to have a good scale, and you need to weigh very small masses, which may require some trickery.
This is not true for everyone
de nile is not just a river in egypt
And science is science
And caffeine is drugs
Half-caf, three cups per day (about 150mg total).
That adds up to a caf and a half.
1.5 caf
do you make it?
I can't find any good roasters that make half caf blends. usually at best they have one mediocre decaf. occasionally there is a really good decaf and i will just blend it myself 50/50 with another coffee.
only one roaster around me makes half caf and it's not regularly available.
When I brew coffee, I use half regular grounds and half decaf. There are some roasters that make half caf, but it's easy to mix it yourself.
I'm in Ontario, I've been drinking Kicking Horse lately and it's decent.
Coffee, yerba mate and cola.
No idea how that works out in mg, but I have 2 or so coffees a day, both of which are double shots, and then normally a mate and/or a pepsi or two
Sometimes I drink 3 or 4 coffees in a day, but I tend to go down to single shots after the 2nd one
However much is in the chocolate bar I eat once or twice a week.
minimum of 1 cup of coffee and 1 cup of tea per day. sometimes more.
i can't drink caffeine after 3pm or coffee after noon.
No need for me to comment. This guy has me covered.
Except I can drink caffeine in the evening too, IDGAF
I snort it directly off of my The Real Book
The most proper use for a Real Book.
Don't bother with the caffeine pills. My brother went through a phase where he was taking these like breath mints, but it was doing more harm then good.
If you feel like you need more caffeine than what coffee or soda provides, then you have a bigger problem that needs attention, and the caffeine is just a bandaid treating the symptoms of the deeper issue.
How familiar are you with ADHD?
They’re about to be very.
There were signs….
I don't, I have a medical condition that can make people sensitive to caffeine and I am one of those people. I honestly appreciate not relying on a stimulant anymore. I had already severely reduced my intake prior to my condition and I don't miss it. I sleep better and feel better in general without it.
Same
Not throwing shade, but caffeine is a crutch.
If you ditched it, it would suck for a few months sure, but then your brain will adjust.
I've been caffeine free for over 20 years. If I stay up super late, or wake up super early, I struggle for a moment, but then I'm fine.
Water is my go to in the morning.
Your body is so used to caffeine, that you're literally medicating yourself for a condition you created for yourself. You need it in the morning on a weird shift, because you always use it in the morning on a weird shift.
Again, sorry for the rant, I just feel very strongly about this scientific fact.
Best wishes to you
I completely agree. I used to be a huge coffee drinker until I came to the realization that it's horrible for my sleep and anxiety, so I weaned myself off it for a few months and then stopped.
Two years without caffeine and I'll never start using it again. It's so nice not being addicted to coffee (and not spending money on it), not feeling wired/jittery and not getting withdrawal headaches. I just wake up and I'm ready to go every morning.
Nice! That's the thing, right? That's the key I don't think people understand.
My normal energy level, once I've woken up for a few minutes, is how I used to feel when caffeinated, after having been on the stuff for awhile.
The low energy they feel, is literally the caffeine addiction talking. Your body gets so used to it, you're not feeling the buzz you felt when you first tried it, you're just maintaining a normal human level of energy, but it feels like a buzz because without it your brain is so addicted that it's suffering for it.
Crazy.
Now I still have a little caffeine for a really bad headache I can't shake. But it only takes a few sips of coffee or pop, and I'm good. It's not enough to make me feel wired, but I still might struggle to fall asleep that night, when normally I don't struggle at all.
Caffeine IS powerful, people just get used to it, but their body is still affected every day.
Loose leaf tea, re-steeped several times over the course of the day. The caffeine content goes down with each successive stepping, but good quality whole leaves will still let you get several cups out of them.
I stop making it at 3, which usually gives me enough time to metabolize it and sleep normally.
When you say good quality whole leaves, where exactly does a person get that?
I don't intentionally consume caffeine. No coffee. Only herbal tea. No energy drinks. There might be some in chocolate, but I don't eat much chocolate.
When I was a kid my whole family were like coffee fiends. Couldn't get going without a cup. I never wanted to be like that.
I quit caffeine. I think I realized something around “this is supposed to be a drug that aides me when I’m tired and need to not be” that caused me to finally try and kick the morning habit. I’ll still drink it, but it’s an as needed thing now.
It took about 1-2 weeks for me to start feeling normal again- I was cranky and very tired for a while. Now I feel the same as before when I was appropriately “caffeinated”
Buying fancy decaf coffee helped curb the ritual habit, too. So I still make lattes and what not but they’re just treats, plus I can drink them in the evening without worry too.
I quit for about a year and a half and by the end just thought I was stupid due to aging/ motherhood. Then one day I accidentally consumed like 2 cups worth (migraine meds have a ton of caffeine!) And I was a super hero that day. I got so much done! I could actually do puzzles again! My brain worked! Then I checked the medicine bottle and was like... oh.
Anyway, I'm diagnosed with ADHD now and realized I've been self medicating with caffeine since high school. I'll never go off it again unless I get actually medicated. I also drink a ton of decaf because I just love drinking coffee
I'll never go off it again unless I get actually medicated.
Tell me you’re from the US without telling me you’re from the US.
My brother has been off his medication while unemployed / interviewing / first 90 days of his new job until his insurance kicks in. Breaks my heart to hear him describe how hard it is to know he's intelligent, but everyone at his new job genuinely believes he's dumb. Kid has an IQ of 141, but without ADHD meds is barely scraping by at his office.
I've previously had a caffeine addiction and didn't particularly enjoy it. So I make it a point to not have it daily. I'd say I usually have 1 small caffeinated soda with alcohol per week and a regular 8.4 oz Red Bull at some point during the week. So probably in total a little under 200 mg per week
The nice thing is that since I don't consume much caffeine if I do want a kick I can have 120 mg and really feel it, but that's usually reserved for particularly long days or days where my sleep gets messed up
I don't, so zero
Probably between 200-300mg. I would never do caffeine pills, as I enjoy my methods of caffeine consumption.
Typically, I'll either drink a 2-cup moka pot, or some espresso. I never drink drip or French press coffee. Too bland. Turkish coffee is also good, but I don't get that too often.
If not coffee, it's usually Monster rehabs or Celsius. Tea is more for enjoyment than the caffeine content.
One cup of coffee with milk in the morning
One black coffee in the morning on most days. Coffee doesn’t seem to affect me but it’s a nice part of my morning routine. If I’m invited to a cafe or offered coffee at someone’s house I might have a second if it’s not too late in the day. Throughout the day, I might drink herbal and fruit teas that don’t contain caffeine (or minimal amounts of it).
There is decaffeinated coffee if you’re looking to reduce your caffeine intake but still miss the process of making and drinking it.
This is my routine too. If I miss that one cup, I get a headache and hate that. But any more and I get too jittery.
Occasionally, energy drinks as I like the fruity taste of some of them. Otherwise, I don't consume heavily caffeinated drinks.
I tried to eliminate caffeine to reduce anxiety in combination with my ADHD meds.
My morning routine without coffee was hard; decaf helped a lot though. Ultimately didn’t kick the addiction though.
If I may be so bold, 400mg is a lot. Your body habituates, so why push the envelope?
My caffeine intake fluctuates in an almost cyclical pattern. I'll injest a lot to the point of ineffectivness, then scale back to nothing, then slowly ramp up again. It's not purposefull, just a natural progression I tend to follow.
Right now, I'm off it completely. I'll stay this way until I have a day where I'm really tired. I'll break down and have a cup of coffee. That's usually the breaking point for me.
At the max, a day could be two Monster energy drinks, four to five 12oz cups of coffee, and an occasional cup of black tea. A few days at this point and I feel nothing from it, and begin to scale back.
I haven't gotten to that level since starting on ADHD meds. Turns out I was self medicating without realizing it.
2-3 regular sized coffee mugs a day.
2 double espressos to start the day, 3-4 more singles throughout the day. Cutoff for coffee is 7pm, and I usually have 1-2 hot green teas in the evening to wind down.
It’s one of my last remaining vices of significance, very tough for me to get going without caffeine and I get a headache by mid afternoon if I don’t get me some by then.
I’m surprised at most of the people in this thread with their minimal intake. Good for you I guess. To the boofers: I get it, but just not for me.
I enjoy a pot of spiced black tea, usually a chai blend with cinnamon, ginger and cloves. Sometimes I will add cocoa powder and pour the tea over that with sugar and milk to make a chai tea/hot cocoa drink that is a highlight of my day.
preworkout, 400mg/day before training, ofc not if I rest
Damn that is a lot to be dumping into your system for a workout. Do you not get jitters?
Is it? I use to take more than this every day, Just recently cut back down to 400mg because of medication
Never really got the jitters, but then again I do mostly cardio, I do feel the effects in my train of thought tho and in my breathing.
Yeah it's nearly three red bulls worth. It's a lot.
There are studies around caffeine before workouts and from recollection they're at the 200mg level.
I boof a couple cups of coffee in the morning then maybe an energy drink in the afternoon. I'm guessing 2-400 mg caffeine per day right up the bum.
I don’t

I don't other than maybe an occasional cup of tea
Eyeballs and I don't have time for your FUCKING NUMBERS STOP BREATHING AT ME
two cups a day, stopping before 3pm. usually shit my pants at around 10
On weekdays, one pot of coffee between 8-11.
Usually a caffeinated soda or two over the afternoon/evening.
I gave up daily caffeine usage. Now I only drink coffee/tea on weekends , and occasionally during the week, when extremely drowsy.
On weekends I drink 1-2 coffee or tea a day.
Coffee recipe: 15 g coffee for 250 ml water at 95° c.
Tea: 1 bag Yorkshire Gold in boiling water, stir, then wait 5 minutes.
Both get half and half with two sugar.
A cup of coffee in the morning and 1 to 2 Celsius in the afternoon.
I miss coffee, but I can't afford decaff right now. Been drinking a lot of roibis tea recently. Tastes good especially with oat milk and no caffeine
I drink anywhere from 24-72fz of tea a day. I don't really keep track. Every year I take two weeks to get completely out from under the addiction, but since I enjoy tea it gradually creeps back. If I could find a decaffeinated tea that tastes good I'd put caffeine in the rear window completely. I abhor the idea of being addicted to anything.
100mg from one cup of coffee (in the style of a latte, cafe mocha, cappuccino etc.) on weekdays at work, on some weekdays a tea or coffee 50-100mg after lunch if I am feeling particularly tired. None regularly on the weekends, except for the odd time I meet people on the weekend at a cafe or something like that. ...and I don't drink colas.
I'm trying to keep it to a level that I don't require it to function.
I don't feel like caffeine even effects me that much. I might have an energy drink few hours before bed and I'll sleep just fine. Same as with coffee - I drink it for the taste. Generally around 3 cups (400ml each) per day.
Rectally, to mix things up!
Whatever two big cups of black, strong coffee is.
I just eat chocolate occasionally :p
I used to drink nearly 2 litres per day. Then I got an allergic reaction to it, including sudden coffee aversion. I no longer drink coffee, because it gives me eczema, not worth it.
Do not overdo your coffee drinking if you like it!
I buttchug a liter of cold brew at 0430 every morning.
im a pop addict. I drink it all day long but I try to switch to caffeine free after 4pm but many times it does not happen or happens at 6 which is when im also eating for the last time which sometimes gets pushed back. Ideally I would be drinking pop from getting up and switching to no caffeine at about 4pm and start eating 2 or 3 hours after getting up and not eating or drinking anything but water after 7pm.
I have 1, 10 ounce cup of black coffee around 7:30am every day. More than that I get jittery and have trouble sleeping. The last time I had an energy drink was probably 2019 and I could only have a couple sips of it before I felt like I was going to take off into the air.
Coffee, black. Minimum two large mugs, but I usually finish the pot.
Boof it; Enough.
Unironically recommend Gamersupps, despite their whole marketing schtick of ridiculous art on some of the flavours, the actual drinks themselves are undeniably good.
None of the canned energy drink blood thinners and aspatame /acesulfamine sweeteners, none of the sugar since theyve replaced it with sucralose, none of the Lead found in other energy drink powders, they actually pay their artists and outright refuse to use generative images.
If you like watermelon sweets his flavour is top tier (and the art is way less nsfw than some)
Honourable mention for the flavour called snake oil, don't watch JFJ but the drink tastes like a top tier apple pie
The last day I consumed a ridiculous amount of coffee was a triple shot long black, two double shots long blacks, and an extra strong cappuccino (or two). All before 2PM. Bad day at work.
Realised I was drinking it way too often and too high of a concentration to be healthy, and it was really affecting me negatively. I quit cold turkey, and I haven't looked back.
Now I can drink matcha and chai (both made at home... Can't justify $8+ for either at a cafe). Only one or the other per day. Coffee is cheaper at a cafe, but unsure if I want to go down that road again.
Right now I have 3 sources:
- mate drinks like Mio Mate (found in Germany) and that's 100 mg a bottle which is all I'll have a day unless I'm really feeling it (so max 200).
- black coffee which I hand grind and brew via aeropress. Just one cup normally. I don't have any idea how many mg that is but it feels as fast as the mate although maybe anecdotally weaker.
- loose leaf tea, which I brew once or twice a day, using old leaves from the day before (if I'm on a streak) and a splash of new ones (unless it's the first day where it's all new). Feels slower but lasts longer so maybe it's more caffeine? I guess it depends on if I'm doing black or green or white etc.
So I'd guess 100-150 mg on average on days where I'm having caffeine. I try to do long breaks between a couple weeks of having it. So like a week or two of drinking caffeinated drinks and a week or two not having it. Not too stringent but just something I'm cognizant of to not get dependent.
Cold brew with a splash of heavy cream. IYKYK. Lately La Colombe light roast. Over ice in a rocks glass. 2 or 3 a day.
If I have any after 3:30pm I take an L-Theanine or eat a banana to take the edge off and protect my sleep.
I drink about 1, 24oz can of NOS a day and those have, IIRC, 350mg of caffeine total. It's 4 servings.
I'm not a medical professional, this is not medical advice.
So there are factors to consider; the strength of the dosage and the frequency at which it's being consumed. Additionally if there are rest cycles.
The positive effects of caffeine are significantly reduced by the frequency it's consumed. This can lead the user to consume more to reach their desired experience.
The negative effects however are capable of stacking. Such as its impact on blood pressure and one's capacity to regulate emotions. Caffeine is also a poor stimulate for someone who is already fatigued or is experiencing weakened attention. It's best at maintaining ones current level of awareness and fatigue.
One could be accidentally poisoning themselves with vitamins or other additives before caffeine becomes the concern.
It's generally accepted that 400mg of caffeine in a 24 hour period for a healthy individual is the maximum dosage.
To avoid a dependency on caffeine and to experience its positive effects at regular dosages. It's best to practice moderation only by consuming it rarely.
Many people will find this unreasonable. The next best option is to practice rest cycles of equivalent proportions. Such as 2 days on, 2 days off. Going larger than that invites negative effects such as withdrawal and tolerance forming.
Everyone is unique, I'm not trying to write a scientific paper. I invite everyone to scrutinize this information and consult with qualified professionals about their own health before following through with information on the Internet. Addiction in all its forms is a serious matter and deserves respect.
Tea, about 6 pints a day, my cup holds just over 1 pint 6* a day. I have mini tuocha for home, tea resin for travel, and some curio tea for variety.
I have caffeine pills in the car, but I've never used them. As for caffeine amount I dunno... a lot probably.
I detest coffee. My caffeine intake is wholly sodas, specifically Coke Zero. It only has 34mg per 12oz, so I don't get a lot of caffeine every day.
I don’t know the mg, but probably too much. In the morning I drink 2 big mugs of coffee, in the afternoon 1 big mug of leftover chilled coffee from the morning brew, sometimes I’ll drink a cup of oolong or green tea in the evening.
I just make sure everything else I drink is pretty much just water or seltzer. I only drink soda when dining out, which is very infrequent, or if I mix a cocktail at home, which is still usually seltzer based.
you are probably drinking close to a 1000mg a day dude. that's a lot of caffeine. the rec daily dose is like 400mg, which is 3 8oz cups.
So what I call my big mug is only 10oz, they just look a lot bigger than my partner’s smaller mugs. I drink 2-3 of those a day. My biggest big mug is 12oz and I typically don’t finish 2 of those in the morning. And the chilled afternoon coffee is often split with my partner. I don’t need it, I just like coffee 🤷♀️
I don’t drink tea every day, just more in the winter and I don’t usually have it when I have the afternoon coffee. I also drink 1-2 seltzers and I always have my water bottle with me wherever I go.
10oz is a normal mug. a big mug is 20oz.
unless you use tea cups as your 'normal' mug or something? tea cups are 4oz.
Your reaction makes way more sense now lol. I don’t really use big and little for ounces, but for the mug size.
These are what I call little mug vs big mug. The left is the little mug, the one on the right is the 10oz big mug. When I drink something like oolong, I’ll have 4-5 brews using the same leaves in the center cup.

~100mg - 300mg/day. That is 1 cup of coffee (espresso-based drink) to 3 max.
I try to limit myself to 1 now unless I am really tired or am having trouble focusing/thinking clearly. I was up to 2-3 every day, but it was messing with my anxiety more than I realized at first.
Around 6 a day. 1 for the drive to work, one guy my first walk at work (11AM), another one my second (1PM) and another on my third (~3-4PM). Then when I get home another so around 7PM and usually 1 or 2 more later on. If I'm having racing thoughts or something hampering my sleep I'll have another then as well. My ADHD manifests stimulants as calming, and coffee was one of the ways I self treated before I was properly getting treatment.
For mornings, 75 g light-roast coffee / 1250 g water made with a French press using the Hoffmann method, divided equally for 4 days per brew (so roughly 250-300 ml liquid each day). Not sure about caffeine content
And then I have some random tea bought from the local Asian supermarket that I brew casually with hot water & drink throughout the day without any care as to how I make it, no idea how much caffeine is in this either
I usually don't take in any other caffeine beyond my daily routine
2 or 3 coffees a week is the most I can do before I start getting headaches. I can drink a tea every day for a week and a half and then I start getting headaches.
A cup of coffee with milk, sometimes two, not sure hoe much, 80-150mg on a given day. Recently, shot of espresso in the morning.
2 cups in the morning, some days 3. I can do another in the afternoon, if I don't need to get to bed early.
Normally one cup of coffee with breakfast, then I get to the office and do a can of monster. If it’s a rough day I’ll have 1-4 more cups of coffee but I cut it off at 4pm.
Pot of French press coffee in the morning. Mate throughout the day. Small cafe au lait before bed.
I should note that I have the type of ADHD where caffeine calms me. The cafe au lait actually makes me sleepy.
I have a cup of black coffee once a day, usually made with an aeropress. On weekends I might have black tea instead, depending on how I feel.
I try not to have my first cup before about 10.30-11.00am, so my body has a chance to wake up naturally. I don’t really know if there’s any science behind that, but I feel like it helps make me less reliant on coffee to get me going in the morning.
I mostly just have one cup a day and then switch to Barleycup (caffeine-free hot drink) in the afternoon, but on very busy days I might have a second coffee around 4pm. I try not to, because if I do that too many days in a row I can feel my body starting to need caffeine to operate at a baseline level.
If it gets to that point, I avoid coffee for a few days to ‘reset’. Again, not sure if there’s any scientific basis for that but it seems to work for me.
In my experience, people build up a tolerance to caffeine pretty fast. It doesn’t take long to go from ‘a cup gives me a boost’ to ‘I have no energy until I have a cup’, which are very different things. I see people saying they drink an entire pot per day or more, and I have to wonder if they even get any benefit from it at all, besides holding off the headaches and fatigue of caffeine withdrawal.
I'm on about the same level. 3 cups a day, or an afternoon energy drink if the day is particularly challenging. I just don't like all the other stuff in energy drinks, so I try to avoid making that a habit.
V8 energy (tea-based) in the morning, coffee in the afternoon. Probably around 300mg per day. Extra if it's a long day.
I do one mug (technically equal to 2 cups) of decaf at home in the morning. When I occasionally visit the office, I consume 1 or 2 cups, depending on the time I arrive. If I arrive late in the morning, I only drink coffee after lunch. If I arrive earlier, I drink one in upon arrival and one after lunch.
No decaf in the office, but I'm not dependent enough on caffeine to notice the difference when at drinking at home and at work.
💉
A pot in the morning if only I’m awake then half in the afternoon. I think a pot is five cups which is really two coffee cups.
Caffeine pills, once in awhile if I'm feeling tired.
1-3 cups of coffee per day. I try to keep it low, with little success.
Varies a lot. Usually coffee but I'll sometimes do soda as well, especially if I have a migraine. Sometimes I'll just do one cup but other times I'll have it all day.
Yerba mate 🧉 when i have a few hours to chill and don't work the next day, occasionally soda too under the same conditions, although I almost never buy soda for myself because it has been tasting like shit in the last few years in my country. I wouldn't say a lot unless i have both because I tend to drink a lot of liquid
A "pot" of coffee every morning sometimes more. And occasionally a Celcius if I'm up late for whatever
I don't intentionally. I have severe ADHD and I've never noticed any effects no matter how little or how much I consume.
Mostly only one cup when I wake up and that's only because I like the taste as caffeine has no or the opposite effect on me. I drink some Redbull-like knockoff (boycotted redbull) every now and then, also just because I like the taste, can and often do easily go to sleep any time after.
If need to do important work and really tired I drink an energy drink with ~160mg, sometimes I'll drink a cup of black tea in the morning
Between 0 and 250mg daily probably averaging 150. Mostly from "gold blend" tea with a teaspoon of milk with the occasional coffee here or there.
I take an "electrolyte" dissolvable tablet the morning after a few drinks that has 75mg in it. Works wonders for cobweb removal.
Very, very occasionally a red bull knock off. Usually if I'm sick and need to suck it up.
2 16-oz cups of coffee with non-dairy creamer to start my day, followed by a pre-lunch SF Rockstar, followed by a post-lunch SF Rockstar, an occasional (1-2x weely) afternoon triple shot latte, finished with an occasional dinnertime 20oz Diet Pepsi... all interspersed with 22 sticks of nicotine.
Might be ADHD, maybe narcolepsy. I still get 10 solid hours of sleep, so it clearly doesn't interfere with that.
2 mugs of 10 oz dark coffee, black, extra strong. I’m currently moderating, trying to stick to that.
I’ve found that k-cups have a similar advantage to soda cans when you want to moderate. You can’t fill up a super-mug and there is no pot/2L bottle to finish. Portion control is crucial
I had to significantly cut back because of my SSRIs so I take 400mg in the morning before going on a 2h Bike ride before sunset.
I completely replaced coffee with these energy drink mix that helps stay hydrated while cycling and is keto friendly / sugar free.
Highly recommend it, normally I drink one pouch (200mg) when I wake up, and I take the second L with me on the bike with some extra electrolytes. It's what plants crave!

I sometimes drink a glass of cola (at most one every 2 weeks). I’ve never had coffee in my life and I hate the smell of energy drinks.
If I don't need it, I don't take any, or maybe a single can of soda in the morning.
If I need it, I take as much as needed to stay as alert as I need to be.
Pump based Liquid Caffeine and flavored water is my preference. That way I don't dink caffeine because I'm thirsty and I don't drink until I have to constantly pee if i'm sleep deprived.
If you just take it all the time, your body relies on it, it's better to reduce when you can to get a better return when you can't
fuck off, bot.
