Then, I noticed he became short-tempered and irritated very easily, which eventually turned into
full-blown aggression. We did not associate this with the drug so he kept taking it. Then we moved and he decided not to get his Rx refilled by a new Dr....I think he was beginning to notice some of the side effects and put two and two together. Anyway, without telling me, he quit the Vyvanse cold turkey 15 days ago. He is still going thru withdrawal. Please, can someone help me?
