We have so many hangover "cures" in Korea and I can honestly, but very unscientifically, say they work ridiculously well. There is one I always take when I drink and no matter how much I drink I feel fantastic the next day (it's actually really odd how well they work and I've always wondered why they are not more mainstream).
