That's definitely good to hear. I hope you don't end up with any nasty side effects; I was on Adderall briefly as a teenager for ADD, and (in addition to giving me a nasty habit of grinding my teeth) it completely destroyed my appetite. Took me years to get back into the habit of making eating a priority, which probably explains why I was almost dangerously thin in college.

Here's hoping the tests find out specifics so you can figure out a targeted (and hopefully longer-term) treatment.
