well, i cant pretend to know as much as Christi, but my understanding is that those medication correct a chemical imbalance, so if you are ADHD (hyper), they will level you off and calm you down. if you are ADD (which are VERY layed back) they will speed you up.
i think they also speed up persons with normal chemical balance (at least those chemicals)
AD(H)D medications are commonly also given to narcaleptics to keep them alert and awake.
but im sure our geek christi will be able to correct all of my blunders..
