I wondered if anyone would go for the zero option.

As a relatively new performer I still get quite nervous & find a drink just relaxes me a little. I've quite happily gone on after 4 pints and been fine but I figure that if 2 is about right for driving it must be about right for playing ann instrument.

Re. the Grumpy Pint - I'm usually grumpy anyway & one pint usually takes me out of that zone!
