I'm writing this on a Sunday morning, and I just came across some information on hangover cures. Fate?
From the time of Ghengis Khan, pickled sheep eyeballs were recommended. Interestingly, this "cure" survives to this day, but with the addition of a glass of tomato juice as a chaser.
Ancient Romans, famous for their debauches, suggested fried canaries, powdered bird beaks, skull dust and dried viper. I think I'd rather have the hangover, thank you.
Modern times, in the Caribbean it's usual practice to put a half-lemon in the armpit of your "drinking" arm. The science-free explanation is to improve hydration.
And, not to sound like your mother, but the obvious cure is to not be there in the first place!! Sort of like bidding... don't over-reach!
