Well with my busy schedule now these days I get maybe 2-3 hours sleep a night school all day then work at night and when I'm not working I haft to work out and I have no choice but to invest lots of money into energy drinks. I drink so many amp's/monsters a day that I'm starting to get severe headaches from it. But now its like I can't function without them. I need some kinda of alternative but coffee just doesn't give me the power I require. Halp!
