"vyvanse has changed my life in the best way! it&#039;s almost like a motivation pill.  i can spend 12 hours in the library at a time studying, with little distractions. i made a 4.0 my first semester of college. i used to always want to work hard and study but could never quite pull it together, and with vyvanse i can! the only downside is the dehydration. remember to drink lots of water or you will get headaches!"
