I do not know the most common, but I take concerta and it has helped me tremendously!.. I went to a psychologist( that I go to 2 times a month) and then she diagnosed me, then faxed it to my regular doctor, that I met with and prescribed it for me. I see her once a month to get a prescription and check in with her.
I don’t know the most common either but my son is on 54mg Concerta and I take a 25mg Adderall XR. I like the Adderall okay it works great for about 5 hours, then it’s gone. I just wonder if there is anything that lasts longer but works just as well?
