I'll drink one beer as I start the round, but then switch to water after that. Couple of years ago when I started playing, I would drink a few more, but one round, I was playing particularly well (for me) and finished really badly. I attributed it to the beers, and decided then and there no more than one to 'loosen up'. Since then, my rounds have been more consistent and fun.
