A good doctor will help you optimize your focus and creativity without you needing to self-medicate or do anything illegal. I'd spend some time setting up an appointment- he/she may find that you suffer from ADD/ADHD and prescribe something- maybe not. If you decide to do something (IMO stupid) illegal, you'll want to know that doctor's phone # and have at least one appointment behind you so that you can call if you screw yourself up. (Doctors are confidential - for your life's sake, talk to a doctor regardless).
