I don't mean to come down on you, but you said you havent' seen this doctor for a year, and you have phoned her? From what I know about Dr's is they don't have time for phone calls and for the most part they don't get paid for phone calls. However they do get paid when you go into the office. It would be your job as a parent to take your child into the office. Also maybe it was a mistake to up the dose, did anyone call the doctor to make sure that is what the does should of been?
As a mother, I think I would go to another Doctor, and tell the new Dr why and what you expect of them. Ask questions about the drugs? The pharmacy can give you a print out of the drugs? Do some internet research find a board on this site with other parents with ADD children, or make your own. Get informed.
I would try to get into seeing another Dr as soon as posible, and go in person not over the phone.
Good luck!
