Looks like the system 'answered' my question. Because I had to register before posting. So here's my second question. I've been diagnosed with hypersomnia and/or narcolepsy w/o cataplexy. I've been on vyvanse for about 4 yrs. Recently I've been fighting anxiety and depression. Have any of you been on a stimulant that long, and have you had problems with mood swings? Thanks!
