"i love vyvanse. it helps me concentrate and helps me in school to work faster and harder. when i get home i immediately start homework and then i just chill with the family until bedtime when i&#039;m tired. i did have insomnia but that went away within about a week. now i sleep like a baby again and it helped me finally start working out which i have been planning to do for almost 2 months now. also, i went from struggling to get d&#039;s to easily making a&#039;s in all classes. i recommend this medicine."
