Hi, my son is 8 and has ADHD, OCD, and tourettes. He is currently taking Zoloft for OCD and anxiety, Remeron to sleep and Ritalin. The problem is, we have tried Dexedrine, Focalin, and Ritalin twice and nothing seems to work! The ritalin helps him focus but he is incresingly nasty and violent when he takes it. He just got suspended from school for threatening to blow up the school. I am at my wits end and don't know what else to try - I have heard that Clonadine , Tofranil and Tenex work for ADHD - does anyone have any experience with any of those, or any suggestions? Please help!!
