Adderall
XR completely sucked. Adderall IR was the best medication that I found until
Vyvanse. Now I think Adderall is horrible in comparison.
I've been taking 30mg of Vyvanse for a few months now. This has been my adjusted dose from trying 20mg, 30mg, and 50mg. 50mg was wayy too much at the time. 30mg was perfect until about a month ago. It lasted about 12 hours, a huge improvement over 4 hours of Adderall IR. However, now it is not as strong, because my tolerance is beginning to build.
