Here's the cure...
I just got back from a few days fishing and drinking in San Felipe Mexico
Those guys party hard until 3am, sleep for an hour then wake up, load the boat up and we're off again for another 8 hours of drinking and fishing twenty miles miles off shore.
Here's what they get for their hangover (crudo) before they go out
They buy this as the store, it's a large Styrofoam cup with chile powders and other stuff, then they pour a beer in it and drink it...BOOM! no more hangover... rinse and repeat for several days
