So...aside from the obvious dodgy date/day choice, should I start drinking now, on my own, at home, so that when I get there I am a bit tipsy, I get the whole pissed-off-my-face thing over by 11pm and I am sober-ish by the time I get home, resulting in (hopefully) no hangover? Plus I'll be really sociable as soon as I get there and everyone will think I'm great and stuff...maybe
