"i just recently started on vyvanse, and it works very well! so i&#039;m 21, and in the past i&#039;ve been on adderall, ritalin and strattera. but none work as good as vyvanse. adderall worked but left me feeling jittery, and ritalin when it wore off i became angry. and strattera that&#039;s a whole nother story! but the main thing i like about vyvanse is i still am me. i don&#039;t feel jittery or like a robot. i&#039;m me just with everything at a more calm controlled manner. the only downfalls are that it takes 2 hours to start working and only last 6-7 hours when i was told it would be 14 hours. but other than that it gets 2 thumbs up and 5 gold stars!"
