National Geographic has an interesting article about some of the strangest hangover cures from around the world. Perhaps they mean "cure" in a way that you’ll never touch alcohol again if you’re forced to take these the morning after:

Germany: Pickled Herring
Pickled or marinated herring is the main ingredient in a sour snack Germans call Rollmops. Considered an excellent way to ward off a bad hangover, they’re made by wrapping fillets of the tiny white fish around bits of onion and gherkin. Rollmops can be a welcome part of what Germans call katerfrühstück, or the hangover breakfast.

Romania: Tripe Soup
Tripe – aka cow stomach – is the go-to ingredient for many Romanians suffering from a hangover. It’s also a common "cure" in Mexico and Turkey, and no doubt many other countries as well. But in Romania, the edible offal is boiled in a greasy, salty soup of root vegetables, garlic vinegar, and cream.

Poland: Sour pickle juice
Polish hangover remedies are all about the sour. Some say that soured milk (which is unpasteurized and has been left at room temperature for a day or tow) does the trick. Others favor sour – very sour – pickle juice, heavy on the vinegar.
