this medicine is a wonder drug for my very large 12 year old. the doctor put him on it about 7 months ago and since then, i have a loving, caring and healthy son. He used to eat all of the time and could not get full making him the joke of school. now he can focus in school and at home. his worrying all the time and trying to passify his worries with food have disappeared. if everything else fails for you or your child, i would highly recommend adderall. by the way, his doasage is 30 mg.
