I didn't read all the replies (just got back to Texas last night from 2 weeks in Thailand!) but to answer your question about ADHD meds that quit working after a while - yes. It is quite common. Especially during the transition through the teen years and into adulthood. It doesn't mean she doesn't have ADHD, or that she's outgrown it. She might be better able to cope with it, however. She's old enough to understand how her ADHD effects her and I'd encourage her to continue to see a psychologist if not a psychiatrist, still, on a regular basis.
