Steve you do not say how old you are. My son, now 20 has ADHD along with a handful of learning disabilities. He was always on the smallest dose possible of medication and never in the summer.

Each year he would start the school year without meds to see if he was able to succeed without them. 9th grade was the magic year. He has been able to be without the meds since then. It took some allowances such as the more complicated classes being in the morning because he was more focused then.

Also he had, and I do not know if this was unique to him, a "superfocus" mode. When something was interesting to him he was able to tune everything else out. He was fortunate to have teachers that really loved the subjects they taught and made the material interesting. His disabilities prevented him from taking notes and his tests were given to him orally, but he excelled in mainstream classes.

I think the key is finding something that catches your interest. My brother was diagnosed in the early 80s and at that time it was a "rare brain disease that only affected boys". And I highly suspect my father had it as well because also had that intent focus. Both are highly successful in their carrers, both have jobs they really enjoy doing.
