"my daughter is now nine and has been on dexedrine for about four and a half years. i know about the med from my little brother and it worked for him. my daughters doctors wanted to try all the new stuff, not one worked so once again i said put her on dexedrine. finaily after about a year they put her on it and she is doing great and on a low dose. so if you have tried the others go old school and use dexedrine it works:)"
