ADHD
"I would give it a 10 but will err towards conservative and give a 9; only because it has a high abuse potential and humans are inherently prone to some type of addiction.  It has pretty much NO side effects if taken as directed for adult add and after 5 years on it, I feel it has stabilized me more than any others.  Adderall is second place for me but it is more likely to make me irritable after therapeutic effects wane for the day.  I have taken Desoxyn before and fell asleep!"
