I am mostly concerned about the caffeine part. Whenever I drink like an amp or energy drink, it doesn't wake me up or make me hyper, I feel the same. the only time it really affected me was when I chugged the 16 oz can in less then a minute, then I was a little jumpy
anyway, why do you think I am not affected most of the time?
