I've been prescribed Adderall XR, and I'm nervous about it. First of all, I'm somewhat ashamed that I'd have to take a drug. I'm willing to work on that. But I'm also worried about what the drug does to me and if I need it. When I take it, I feel energized and awake, and I can really focus on things, and I feel way more interested in things. What are the expected effects on ADD and non ADD people?

Also, how is amphetamine different from amphetamine? I want proof (in the form of multiple long-term studies) that Adderall XR won't give me brain damage or other problems.

These are very important issues in my life. Please let me know anything you know. Thanks
