I don't know how common this is, but I have all kinds of performance enhancers that I couldn't live without. For example: Emergen-C - packets of vitamin C that you mix in with your drink. Very restorative; Ginseng - Amazing the way you can run so much more and tire so much less; Sam-e - Keeps my mood in balance (don't get nearly as angry or frustrated) plus it's great for the muscles and joints keeping the body looser and more flexible during play. I usually take all three, EmergenC and Ginseng extract in my drink and 400 mgs of Sam-e in pill form. Anyone else using enhancers?
