| 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. |
