"My son is 13 yrs old and has been on Concerta for a couple of months for ADD.  He is doing great on it.  He is able to focus and his grades are back to A's and B's.  One thing I like about this medicine is that he is not losing weight on it.  He still has a great appetite.  The first two weeks his appetite was affected a little but now back to normal.  I would recommend this medication.  I even get positive feedback from his school."
