ADHD
"When I first started on Vyvanse (30 mg) I thought it was a miracle.  I was social, energetic, and losing a lot weight.  After about 6 months on it (40 mg) things started to change, I began having horrible crashes where I would experience depression, OCD type behavior, and thoughts of suicide.  Trying to get off it it brought about terrible withdrawal symptoms; I gained a lot of weight, was lifeless, and extremely depressed.  I really wish I never started this drug. I noticed a lot of people loving this drug have only been on it for a short amount of time, so come back and update your review when you have taken it for 6 months to a year.  The rebound affect of stopping it has been awful."
