I have just been recently diagnosed as having adult ADD about Oct or Sept of '04. I am currently attending a local college and am doing well. I am taking 20 mg of Adderall XR to increase my focus on school and reduce my impulsiveness. Though I am only 22 mentally on some days I feel like a teenager. Meaning oversensitivity, some what of lacking self confidence, over analyzing the simple stuff, when it comes to decision making having to ask for opinions, making wrong/stupid decisions, etc. Why do I feel(on some occasions) I can't grow up mentally? Are these adverse affects of Adderall XR? I can clearly see a difference when it comes to focusing and some change with some impulses. This has driven me, my boyfriend, and classmates crazy. Can anyone help?
