Vyvanse
"I'm 24, in gradschool and I've been taking the 70mg for about four months.  At first I lost ten pounds but now have maintained my appetite.  When I don't take it I do feel an uncontrollable desire to eat a lot.  I have difficulty sleeping at night and sometimes won't fall asleep until 3 or 4 am, and I take the medicine as soon as I wake up. I think it works best a few hours after taking it. Feel no anxiety and accomplish a lot- but then wears off by the afternoon.  Also I was prescribed an anti-depressant before but I feel this somewhat takes care of that. I still prefer taking Vyvanse now but I do think I'll stop for a while after graduating because I'm not sure about the long term effects."
