this is a commonly used drug used for kids with ADHD, (attention deficit hyperactivity disorder) which i happen to have. it helps people concentrate on their work, and pay attention. If youre like me though, you pop them and stay up for days on end with no sleep, and become increasingly alert and twitchy :) but that MIGHT just be me.
