Caffeine is good for staying awake, not necessarily particularly good for studying. For studying, you want methylphenidate (Ritalin, Concerta), or mixed amphetamines (Adderall XR is best). That is, assuming you're willing break the law, haha. Those give you ridiculous energy (but in a really straight-awake way, unless you combine with caffeine or take way too much, in which case you're going to go a bit Tourette'sy), but also make you really, really focused.

And really, really annoying, hyperactive, irritable and most often drug-dependent. Good luck with that.

Make sure you get plenty of regular exercise--that way you won't get antsy. Also take fresh air breaks while studying--go for a quick walk or jog for a few minutes, even while thinking about your subject. Keeps your brain fresh and sometimes a few minutes of reflection away from the books helps topics fall into place.
