My son is on Concerta also and does wonderful with it, he use to be on the Resperiadal but he was getting depressed and was saying he didn't want to live, he also has the outbursts, so they took him off the resperidal and put him on seroquel and he is doing great he still has his outbursts when his meds need to be increased but otherwise he has been doing great, and is very happy, I think it just depends on the child on what medication works for them. It took us about a year before we found the right one for our children. I wish you luck, it will all work out, but you are not alone.
