"i have been taking vyvanse for a couple of months now for my adhd and bed, 40 mg seems to work fine with minimal side effects. my doctor recommended that i only take it on work days and give my system a break on weekends. however, i noticed that my binge eating has gotten way out of control on days that i don&#039;t take it, to make up for the loss of appetite during the week i guess. i mean, i eat constantly!  is anyone else having this problem?"
