"high schooler, last year failed with d&#039;s and f&#039;s now i have a&#039;s and b&#039;s across the board. i&#039;m taking 30mg of vyvanse every morning, and it has turned my schooling in a complete 100% success. only negative thing i can say, i&#039;ve been having very short tempers. anything can make me go off, i had it before taking medication but now it&#039;s more common for me to get very faster. other than that no complaints! for a school setting this medicine is amazing."
