Our daughter is 10, has norcolepsy and cataplexy. Is put on Concerta 18mg a day. A lot less cataplexy, but she still complains of nightmares and bad night sleep, also does a lot of day time sleepiness on any chance she gets. Dr. wants to raise the dosage to 36mg. We are new to drug, need some input on 36mg for a 10 year old. Thanks.
