My son has ADHD and a few months ago he started taking Vyvanse. So far I have not seen any negative side effects and it is the most effective med he has taken-unfortunately he has tried a lot of others, this is the best of the one we have tried. I understand your frustration it seems like most of the time you are just spinning in circles and no one is really helping. Keep trying, if you can switch doctors until you find the right one(s). Good luck.
