"just started taking vyvanse. before i was taking adderall 30mg xr and i&#039;ll tell you vyvanse works so much better. vyvanse stays active until it wears off. the only bad part is, sometimes it will stop working for like 5 minutes and then it will start working wonders again. it helps me get my work done and it helps me stay in control and very focused all day long while i&#039;m working. before i started taking vyvanse i couldn&#039;t concentrate what so ever. and i would never get my work done. it also makes me feel the best that i have ever felt in my whole life. if it wasn&#039;t for vyvanse i would probably be fired. i&#039;m 24 and i finally get to enjoy life. to the people who made vyvanse god bless you."
