Does anyone have any experience in using Daytrana for over 9 hours.

I know it is recommended for 9, our doctor says it's ok to go over 9 to cover home work time. I obviously have concerns based on everything I've read and want to insure that there is no increase of side effect potential by leaving it on longer.

Any experiences would by helpful, by the way it seems to be working very well for my son other than the loss of appetite.

Thanks in advance
