Only thing that I wondered reading your post is whether you are trying a high enough dose of meds. We didn't see any effect either with lower doses. With Daytrana, we had to go to the highest dose possible (30 mg)--the 10 and 20's didn't make any obvious difference. If you've gone up to a high enough dose, then it seems strange that the meds don't help at all if it's really ADHD. You could try some non-stimulants and see if they do anything before giving up. There is a book by Amen "Healing ADD" about ADHD and the different types and how stimulants can actually make some forms of ADHD worse. It also suggests some over the counter options and other alternatives.
