I was just reading joohang's "tired" thread and someone mentioned caffeine. I realized that caffeine does not affect me at all. Well, it makes me pee a lot, but it has no effect on my alertness or sleeping habits. I could drink a gallon of black coffee and drop straight off to sleep. I know this for a fact because I've done it before. I've tried to stay up all night for one reason or another, and drank a lot of coffee and still fell asleep.
Is this just some physiological thing? How many other people are unaffected like me?
