Does Anybody Do Business Shots?

Or 1-2 shots of some sort of spirit to ‘steady your nerves’ before something important. I’m talking 4 oz of liquor at most. Not for inebriation, but for the sting of liquor in your body?

I do this exclusively with tequila or whiskey. I drink it real slow. Let it slide down my throat. Feel the burn. When it’s over I feel a little more ready to do whatever I have to do. Anybody else do this?
