Well, after a recommendation from a friend, I took a pill of this to help me study (huge test tomorrow, lots of material to cover in a short amount of time). This shit got me geeked. I did some research and found that no one really knows how it works, but its used to treat ADD and narcolepsy. Anyone ever heard of this or taken it? I don't want to take it if its going to screw me up in the long run. thoughts?
