This is something I do personally the morning after a particularly raucous mixer. I'm not sure if this is more of a nostalgia-fueled, conditioned placebo effect, but the Coke genuinely seems to settle my stomach, give me the perfect concentrated dose of caffeine, and improve my mood.

Hydration is super-important in nursing yourself back to working shape, but there are smarter, more efficient ways to take you there. That being said, it is important to properly hydrate -- and while there are better ways, this is not a bad way, per se. You just have to make sure you don't overdo it. You don't want all that stuff sloshing around inside your body, especially on an empty stomach. That will only make things worse.
