I wouldn't get angry so much as I would become depressed or robot like like the OP stated, except I had no reaction for anything. People would ask me a question and could barely illicit an answer out of me. It was like I couldn't think. I was completely blank. And then when I'd go to talk and it would be extremely hard for me to talk. My throat would be scratchy, my voice gone, absolutely no moisture in my throat or mouth. Granted, I was smoking .5 street meth (or blue bell as I liked to call it : P) and not taking Adderall. I find it so odd that I became a dope fiend (dope=meth where I'm from) before I'd ever even taken a Vyvanse. I still to this day have never taken an Adderall, and I will on occaision, for the purpose of pulling an all-nighter and all-dayer the next day to get something done for class, take one of my sister's phentermines, but that's all I do as far as stimulants go now-a-days. I can't do x anymore because of my Rx meds that I NEED, and apparently they fuck with psychs to where they don't let you trip, so all I do is opioids lol.
