I'd recommend that you get off caffine. I used to have the same problem staying awake, would drink all sorts of energy drinks to keep me up... but nothing worked. I am up right now @ 2am working hard on a paper, drinking cranberry juice. I did the caffine withdraw thing over spring break. Just stopped drinking anything with it, had a horrible headache for 2 strait days. It was worth it!
I try to eat healthier now, less sugar and the like, and now that I am off of it, just the littlest bit will keep me awake.
In short, get off caffine for like 2-3 weeks and just try to get more sleep. Then after your body is free of it, you can go back to it in small quantities to keep you up
(back to paper now, damn CEG distractions
)
