The 5 Hour Energy drink is pure crap, at least it didn't do anything for me. It's a 2oz shot, with vitamins caffeine and other stuff. Label Info Here Why the hell would they put 8333%, or even 2000%, of your DV of a vitamin in there??

I got a quick rush from the caffeine, since I have weened myself away from Mountain Dew, but other than that there were no noticable effects. I still went to bed at the same time just as tired as always. I took it in the evening to see if it would make me stay up longer.
