adhd
"Many doctors seem to be convinced that if you have an AD disorder, you simply can't get high on stimulant medications. This is NOT the case at all.

First off,  stimulant medications in general work well... very very well. 

The first day I took adderall I was at school. About an hour after I took my dose of 20mgs I started to feel this awake, alert, energetic feeling inside. I liked, a lot. For the next 5 hours all of my boring subjects became very interesting and I became a very social person. After about a month, those effects started to go away. I went to the doc and asked for a dose increase. Without any hesitation, he DOUBLED my dose to 40mg. I quickly found my self abusing adderall. 1 year later and I'm now in rehab for drug abuse."
