I posted about my son taking 5mg, then 10mg of Focalin as the 5 didn't work. But on the 10 he complained of dry mouth/thirst and now refuses to take the Focalin. His psychiatrist suggested we try Concerta. Is anyone's child using it, or tried it? Did it work? Side effects? Seems like it may have worse side effects than Focalin, especially for a child with anxiety. My son is 8, almost 9 with ADHD, anxiety, Aspergers, PPD-NOS.
