Hi all. Ive bn on adderall for bout 6 months now. started out on 15mg xr, slowly building my way up to two 20mg ir's daily. My question is: Can anyone tell me why my doc will not change me back to the Concerta ? With the adderall damn near impossible to get, theres sometimes a 2 to 3 week gap inbetween my scripts. Thus, the pink generic made by Banraxy makes me sick and sets off my migraines.I like the med but with this shortage problem comes others. I simply want to be on a med consistantly. Anyone know the deal
