Strattera….I hated it…. diagnosed as an adult. was constipated for the entire year I was on it. hope this is not the case with your son. sorry to be blunt. most doctors HATE it. How about INTUNIV instead of the strattera….While I have heard that vyvanse can make some angry, it does the opposite for me. Really helps with impulse control…..does NOT last more than 8 hours though.
