Right on Dave.  I never drink when I work.  Since I work just about every night, I seldom drink at all.  I have used Cranberry Juice or Orange Juice over the years, but lately, just water.  It is low in calories too.
I instruct the bartender, if somebody insists on buying me a drink, to not put liquor in it.  It's hard enough to do what we do when we're sober.  I have good friends who are musicians who feel like the liquor loosens them up and makes them better.  In most cases it just makes them THINK they are better.
