I have ADD, which was caused by my exposition to 300 ppm carbon monoxide as a kid. I recently started taking Vyvanse, which durasticaly improved my grades, but has left me with some side effects that I don't know how to deal with. But, I don't want to have to stop taking Vyvanse. Ever sense I started taking Vyvanse I have been acting a little OCD, having minor headaches, having major mood swings, a decrease of weight and appetite, and several other side effects.
