It is a matter of prevention. You get a hang-over for two specific reasons:
de-hydration and methanol poisoning. There's not much you can do about
the methanol, but there are two things you can do which take care of the
de-hydration...

1- Drink a lot of water before going to bed: this is a given. Since alcohol is
a diuretic, you tend to lose a lot of water so it IS important that you drink a
lot of water.

2- Drink something with a lot of electrolytes: gatorade is a very good source.
