I'm 22 years old and I've been prescribed Adderall XR 20 mg for about 6 months now. Adderall XR has made me have insane mood swings to the point where I want to throw things and I flip out. When I get upset about something, it turns into WWIII and I can't control myself. I've also been very depressed. It does help me focus. It has helped me tremendously with school and work.Is there anything else I can take? Stratera doesn't work for me. Also, I'm afraid I'm going to gain weight and lose focus if I get off Adderall.
