I'm a college student and I need to spend MANY hours studying but I find that after a short period of time I just fall asleep. I workout every other day and eat right. Energy drinks are too much money, I'm hoping there is a supplement out there that will help me concentrate and give me more energy for the possible "all nighter" of studying. I don't get a lot of sleep to begin with either. I am not making this thread to get answers like, get more sleep, etc etc, because in college thats simply not going to happen. I'm looking for suggestions on a supplement in pill form. Anyone know of anything or tried any? I know of vitamin b12 but I was wondering of any good complex's out there too...?
