ADHD
"My 7 and 11 yr old children take 18mg and 36mg respectively. The 7 yr old also takes a 5mg Methalin tab at about 3PM because she melts into a screaming pile of shattered emotions otherwise.  Actually, that&#039;s how she was ALL THE TIME before she started taking Concerta. The 11 yr old recently increased his dose because he&#039;s getting older and bigger.  He was singing/humming/noise making in class again (which is what clued me in to a higher dose. He started taking Concerta because he couldn&#039;t access information when doing homework. The information was there, he just couldn&#039;t concentrate long enough to access what he needed. VERY frustrating for him. He isn&#039;t hyperactive like the other child, so he was diagnosed at a later age. Side effects: sleepless until 12AM."
