2 pints of water, followed by coffee, about 3 mugs. A big greasy breakfast (as per Melissa’s trip to the Waffle House. Except grits. I don’t know what they are. In the UK, grits are underpants. Or is that grots? Anyway…)
Paracetemol. Watch a good film. Masturbation. Lots and lots of masturbation.

I do this with every hangover. I still haven’t ever cured a hangover, but if you follow the above, at least you’ll have fun.
