Coffee.................?!
Do you find it odd, if your dead tired, and you drink coffee and it still doesn't keep you up, I experienced this the other day, I was tired, drank a cup of coffee, and still fell asleep half hour later. not enough caffeine I suppose?
Answers:
One cup of coffee won't keep you awake if you are really tired. Caffeine is a stimulant, but it is not that strong of a stimulant..
I drink coffee daily. By no means does it affect my energy exertion. But for some people, caffeine effects them. It's different for everyone.
need more caffeine
