i disagree with the above, when it took xanax and d-amph it seemed about 10x more euphoric, all the jitters and anxiety assosiated with it gone, but i seemed to black out a lot more as i'd have to take a higher dose of xanax, about 2mg 4 times a day, same with mdma, but everyone is different i guess
but for ritalin... i'd use it on the come down when you feel like your world is over :D
