I have a son that just got off Adderall XR because of failing grades and also side effects. It wasn't helping so we quit. We had a script callled in ffpr Strattera but never picked it up. We tried the route of a vision therapist. She works with ADD/ADHD kids also. She list her proffession as a behavioural optometrist.She is wonderful. She believes my son was possibly misdiagnosed with the ADD, and she believes he was positively misdiagnosed with his LD.
This is not a quick fix for my son but it will (hopefully) change his life forever. I have read ALOT on this and not one article, opinion, or statement was negative.
I wish I had more advice to give you, but my son was just so sickly looking on the meds,and he lost so much weight so darn quickly, that we couldn't take it. He had low D's in all 4 classes. Since stopping the meds. he was more alert than he had been in a long time. We did start him on the Gingko Biloba 3x/day and fish oil(omega-3 1000 mg.) 1x/day. He has in 4 weeks time brought up all his grades to mid range C's. His teachers have all passed on to me that he is participating more than he ever has, he is alert, focused, and doing quite well for the first time. He is more alert around here also.
I do not envy you in your struggle, as I have walked that road, and am still finding my way. I pray this is our answer. I hope you find yours. My son by the way is almost 16. Freshman in HS. Sweetest boy, heart of gold, a little immature for that age, but he's my boy

He also has that middle child syndrom on top of all else. Poor thing
Good luck ans wish I could give you more info, but I just don't have any.
