The condition, as you call it, is a subjective one; did you ever ask your son the whole time you were pulling out your hair trying to figure out why he wasn’t just like all his behaved friends what he thought about the treatment?
Has he ever asked you why you didn’t accept him the way he was?
As a matter of fact, we did. The first day on his meds he came home and told his Mother, "MOM! I did ALL of my math! And it was EASY!!!"
We did not come to this as an easy decision. When his teacher first suggested that might be an issue, we took him to our regular family physician who said after not even examining him (and I quote), "He looks normal. But if the school thinks he needs a prescription, I'll write it."
We left and never went back. We found a new pediatrician who in the first visit spent two hours with him. She interviewed us, interviewed his teachers. The diagnosis was a two month process.
We were never "pulling our hair out." As I said upthread his issues weren't bad behavior, but distractability. He was never the squirmy type. It was never a matter of getting him to "calm down."
