Lisdexamfetamine
adhd
"I'm 19 years old 4'11, small-framed, and I weigh 85 pounds. I didn't notice a great change in weight when I stopped it for one whole summer when I was 11. I just gained 4 more pounds. Nonetheless, I'm not underweight, bulimic, or anorexic. I've always been thin and petite.
I'm on 60mg of Vyvanse for ADHD currently, but I've been prescribed it for awhile.
What can I say about this medicine? It's great! Yes, it suppresses the appetite a little, and sometimes I have to force myself to eat. 
This medication doesn't alter my personality oddly like Adderall. I'm still me, just more focused. My only complaint is that it mostly wears off in the evening when I need focus. I'm a singer too, so dry mouth is a side-effect that I could do without."
