Amphetamine / dextroamphetamine
"I started out taking the regular Adderall version, but it didn't last long and made me have horrible crash periods and steroid like rages. So far, the Adderall XR seems to be working better, but it does reduce my appetite substantially. I've had to start taking weight gain supplements to ensure that I maintain my proper weight. If I miss a dose, I feel pretty lethargic and extremely sleepy. 

However, the medication has allowed me to read and focus better than I ever have, and I seem more motivated. I'm also able to talk better with others, and my social skills have definitely improved."
