"i am a 14 year old girl and last year when in 8th grade i found out i was add. my doctor prescribed me vyvanse. at first it took me a couple weeks to find out what worked for me (when to take it, eat first or after etc.). my grades at the time were horrible and they went up after i started taking vyvanse. i have had a few of the side effects (dry mouth, loss of appetite, weight loss etc.) but this medication helps me focus a lot more."
