Amphetamine / dextroamphetamine
"Been on adderall for about 4 yrs total. I started on 20mg XR, which I thought lasted too long and I couldn't sleep at night. So I got switched to 20mg IR tablets for 3 yrs. My tolerance has grown since so I recently bumped up to 30mg IR tablets.

As a person suffering from ADHD, adderall was a life saver. I was struggling in school, could not focus at work, my room/car was a total mess, I could barely hold a conversation. Since getting on adderall none of those things are an issue. It has helped me greatly in being able to function in everyday life. It's increased motivation significantly.

My only complaint about it is the duration, IR is too short & XR is too long. Also tolerance develops quickly, I can easily handle about 40-50mg at once"
