adhd
"Got this for ADD and my chronic fatigue. 

It changed me. Grades in school went from 60s-80s, I could actually focus long enough to plan my life and pay attention. Only problem I had was the tolerance, although my dosage was raised and now I can take it regularly without feeling it, it made it really hard to sleep if I took it to late, and if the dosage is too high, or you are just starting, you get a really unpleasant buzz. Even though that buzz makes you super motivated and lets you get stuff done, it makes it really hard to relax and makes you more prone to panic attacks."
