I am also new to message boards, I was just looking for more info on adult ADD. I was told about 10 years ago that I had it I am now in my late 30's. I've been on adderall and ritalin and now I am taking adderall xr 30mg. If I miss a dose I feel like crap and can not function. I am very concerned about the long term effects from these drugs. Does anyone know about them?
