would coffee qualify? although not doctor prescribed, it works well.
I remember reading (some years back) that a little coffee helps ADHD kids settle down - and remember how, when I was about 5, my parents started giving my brother and me each a half cup of coffee every morning. I stop after 2 cups each day - more gives me the 'jitters', and less isn't satisfactory.



I just want to know if there is anybody who is on any kind of attention disorder or mood disorder medications which have actually enhanced their chess focus/performance.
I do mean doctor prescribed, not junkie behavior.
