Anyone have any luck with Vyvanse? My son's psychiatrist wants to try him on Vyvanse because Adderall is just not working for him. He's only on 10 mg daily of Adderall, but everytime we try to raise the dose, he gets very emotional and can get aggressive and mean. I told the psychiatrist that I know he needs more, but I am not raising adderall and that we need to try something else. He mentioned Adderall XR or Vyvanse. Is Adderall XR made like the short acting adderall? Anybody have success with Vyvanse? My son is 5 yrs old, almost 6.
