Anyway you do it, it's going to hurt
Seriously, I'm confused. One week, hangovers are basically incurable. The next week, of course they're not. This week, they might be, but only using an exciting new supermolecule designed for removing specific toxins from the bloodstream. Decide, people! I've only come across two effective methods of dealing with hangovers: 1) sleep for three days, or 2) keep drinking.
