How much coffee in one day is TOO much coffee?

[Phishfan]

Add me to the list of non-drinkers. It does nothing noticeable for me. My ex and I use to have a cappuccino machine and I could drink a cup then take a nap. Stimulants have to be pretty strong to affect me.

i guess i'm a casual coffee drinker.  3-5 cups per week, but its usually a 16-oz cup.  I can easily do without it, but sometimes I have it if I am (a) really tired or (b) there's nothing else to drink.

I have never had a cup of coffee or any of its derivatives.

Caffeine really doesn't do much for me. If I'm tired, I'm tired. Even if I haven't had any caffeine for weeks, I can still drink a large cup an hour or two before I go to sleep and it won't affect me. Maybe that's just because I'm chronically sleep deprived, I dunno :/

I do get withdrawal symptoms, though. Not with coffee, but  used to drink about half a gallon of Coke a day and when I didn't get my caffeine, oh man, that was bad. Really bad headache right behind and above the ears. I get them now, even if I drink stuff like Coke in much lower daily doses for a while (say 16oz a day for a week).

At times when I've been insanely busy, I've tried caffeine pills, tons of coffee, Red Bull, etc. Nothing's worked. When I get tired, I'm tired. Period. I remember falling asleep in school during class, despite trying my damnedest to stay awake. Even during fairly entertaining classes I sometimes dozed off, especially if the lights were turned down for a presentation or something. I would try to pinch myself and all sorts of other crap. Nothing doing, when my body says it's tired, it's going to sleep. (No, I don't have narcolepsy).

One large cup of black coffee is good enough for me.  Preferably the Dunkin Donuts or McDonalds brand. 

No sugar or cream, as that's what kills you faster.

I drink the equivalent of about two 6-cup pots a day. Sometimes, as on days when I'm working in town, I actually brew two pots myself. Other days, such as when I'm out of town for work, it's storebought (Sheetz, Wawa, Dunkin Donuts, or Starbucks). I drink it black.

Caffeine itself doesn't do much for me, I just like the taste of coffee. I started drinking it when I was 18 months old, with my great-grandfather, who lived until I was about 9 years old. Although at the time, it was probably more sugar and cream than coffee. Due to my body's non-reactiveness to caffeine, I can (and do) drink it at all hours of the day, often as late as 1 or 2 am. (I just finished a 16oz from Sheetz while watching Conan).

I once took an energy drink called Spike Shooter at 7am & was wide awake up to 3am trembling like a heroin addict. 300mg of caffeine in a small can. Bad stuff man avoid it if possible unless you need to cram.
Another thing concentration has alot to do with it. For example 200mg of caffeine in a small can is alot worse than a large can with the same amount

I never understood why people took caffeine to help them study.  It keeps me awake, sure.  ...but I get amped up.  It's not really the kind of brain built for studying.

[Phishfan]

I took caffeine pills to study late once and went to sleep. The stuff just does nothing for me.

I don't like coffee, and ingest a minimal amount of caffeine. For instance, when I do drink a coke, it's diet caffeine free.

[raptorsfan29]

i don't drink coffee, i limit myself to non caffeine drinks for the most part. i drink some soda, but maybe a glass a day at the most. sometimes none at all. 

But how much is too much coffee? When your friends start to say "whats with that twitch"

You mean brown water?

[AprFools_Phins]

No coffee for me either- at least not on a daily basis. I will occasionally stop at Port City and get some kind of drink (the really fattening frap. drinks)- but with my kidney disease I'm not allowed any caffeine- and when I drink pop it's usually sprite which is caffeine free too.

The combination of sugar and St John's wort work better than caffeine for me when it comes to late night research marathons, but I'm usually washing it down with caffeine anyway.

No coffee at all for me, I don't really like it.... diet coke on the other hand.... I have the market on that
