I am seeing my doc in about a week, I was precsribed vyyvanse but my shiity insurance wont cover it.They said they will approve Dexedrine, Focalin, ritalin, and adderall.I was diagnosed with adult ADHD but never taken any amps before, so anyway my doctor will script me whichever one I decide to try anyone and everyone with amp experience know what I should start with? Which ever one im probably gonna start out with 1/4 dose just in case I die of heart failure.
