My son did fantastic with Lamictal. There was a dramatic noticable difference. That was his only medication. We tried adding Lexapro for anxiety issues, that was a disaster.
He stayed on Lamictal for almost 3 years. When he was doing well for a long period, we began to wean him off.
He is currently taking concerta on school days. I do not see a difference, but he insists it helps.
He has some rough days, but not angry like he once was.
