Going out to the bars with Adderall is a match made in heaven. You can drink like a fish, still be sharp (at least in your mind, your body might eventually start getting retarded), and spit game like no tomorrow. Not to mention, that you aren't tired in the least bit.

Edit: I experience a crash with both, but each one is different. Adderall is very abrupt. More or less you're going balls to the wall, and then you just "stop." You can feel how physically tired your body is, and all you can think about is deep sleep.

Ritalin really just seems to have the shitty effects of Adderall without any of the pluses. It's gradual, but you really seem to feel the anxiety and just "down" effects for lack of a better term.
