we used to have this problem on snowboard holidays but not anymore
at the start of the week we buy about 5 plastic two litre bottles of water from the local supermarket and keep them by the bed. we go out and get wasted then just before bed, pop a couple of Alka Seltzers into the bottle (you need to break em in two to get them through the neck) and wait a couple of minutes before drinking the lot
get up at 8am, get breakfast and out we go back on the slopes with no hangover, works a charm and I do it every time I have a heavy night now.
it seems like a lot of water, but its pretty easy to drink with the Alka Seltzer in there, plus you are drunk so tend to feel capable of anything.
