Sounds counter-productive, but to build up a better resistance to alcohol, little and often is the 'key'.
When I played rugby and cricket, I would regularly drink vast quantities of beer, and, although I'd be hungover massively, I wouldn't be wrecked during the course of the evening - just the nausea and headache the following day.
I let my hair down yesterday and had four pints of Newcastle Brown, and although I wasn't drunk, I had a rotten headache earlier this morning. I don't drink often these days, though, as it's £8 a pint here!
So the CC Christmas party in London should be fun
(what, with all those real ales on offer and CM shouting the rounds!
).
