Is Prescription For Intake Of Adderall Necessary?

when i was young 16 - 22 i was prescribed ritilin and over the years i havent been taking it anymore as i felt it wasnt effective anymore ... however recently i have felt as if i cant focus on anything for a long tperiod of time, and im 38 now. I have tried adderall 20 mg a day which seems to work much better for me and i can now complete the tasks i start and i dont feel woozy like i did with ritilin. Is there a way i can get prescribed adderall without having to go see a psychiatrist?
