"i cannot stress enough how thankful i am for this medication. i had always been a very smart kid but my drive and focus would come in very short bursts if i was interested otherwise i could not have cared less. i was prescribed 30mg of vyvanse initially and that was upped to 50mg which i have been taking for over a year now. my grades went from a 3.2 gpa to a 4.0 within a semester. i excelled at work. i am a more alert driver. like everyone else has said, i feel as if my thoughts are all organized the way they always should have been and i am finally able to catch up on life, which always seemed out of reach. i strongly prefer this medication over adderall ir which i tried. there are no negative side effects except insomnia."
