"my son who is nine was just started on vyvanse for add. he was not hyperactive just couldn&#039;t focus.  we struggled with from preschool to third grade. held him back in first that helped a little. then third grade about killed him. medications were my last resort. scared me to death to put him on medicines, 100% difference. teacher said it was like a fog lifted. i&#039;m like wow. decreased appetite only side affect. but not bad."
