We tried the usual medicines. Ritalin,
Strattera, Adderall, Concerta, etc...nothing seemed to work but when all was said and done, my son developed vocal tics. These haven't gone away for the last couple of years.
He is now on Tenex, and Clonidine, for both the ADHD and the tics.
We've noticed that when he's getting sick, the tics are at it full force. And within the last 3 months he's had to obsessively go to the bathroom.
