Thank you Miles...but this really wasn't helpful. Our son has been diagnosed with PDD (autism), ADHAD and Tic's...we have modified his diet (no wheat, dairy, caffeine, msg, caramel coloring, etc..) done countless behavior modifications and have seen more specialists than you can imagine. We did not choose med's as our first choice (they were offered to him 3 years ago and we declined)...we have been working to help him function in the real world since birth. We want our son to succeed and this was our last resort. So again...does anyone know how long it would take (or what process it takes) to wean an 8 year old off of this dose of medication if a problem would arise? Thank you.
