I’m hungover. Will a dry fast help me feel better?
This may not be directly applicable, but the most complete hangover cure I ever experienced was by doing the following:
This was possibly not safe, and definitely not pleasant. But I did seem to get good effects by “sweating out” the hangover pretty thoroughly before rehydrating, so it seems like dry fasting might have a place.
(That said, while that was the most complete hangover cure I’ve ever experienced, the most consistent has been from a specific preventative product. So mileage varies in all sorts of ways.)
