Another Life Rule

I realised that when I say "I don't drink" what I really mean is:

* Vin must never drink more than two units of alcohol in one day, unless he is in a clear position to accept the very shorts odds that he must then write off most of the next day till about 16:00. This is so that he can lie in bed going "aarrrggh, my head hurts" and listening to Radio 4 very quietly, punctuated with the odd trip to the toilet to throw up.

That takes quite a long time to explain, and simply saying (and implementing) "I don't drink" makes life a lot easier :-)
