My daughter was dx'd with ADD/ADHD and really never slept more than 2-3 hours a night... Once she started med tx she was able to sleep normally. She has been on Focalin, Ritalin, Adderall and Concerta. Ritalin didnot work at all....but the others did. She had to be rotated occassionaly, but has been on concerta for the past 2-3 years and does fairly well on it. the only problem is she needs 18 hour coverage in freshman year of highschool due to the long days....
