I was curious if anyone had had any issues with not sleeping while taking Adderroll? I am trying some other options with the help of my doctor to try to be able to sleep at night for more than 3 hours at a time. It's so frustrating because I notice a HUGE improvement in my concentration but then after so many nights of very little sleep it catches up to me and I have to go off the meds to rest up. My doc switched me to Ritalin - SR (the generic of that). Anyone have experience with this?
