So I guess a lot of people are going to be running with hangovers. Lol.
To date, running has been the best (though most painful) cure for a hangover I've ever found....many years ago, a GF and I were slated to run in a 10K; the night before was a friends birthday party. Tequila was involved. I kept trying to bag out of the run, but the GF was having none of it, so I gutted it out...and felt outstanding (though smelled markedly ripe) afterwards...the only thing that really saved me was that she could not run more than a mile or so without stopping and walking - had she been in better shape, I'd have been hurting something awful...
