I suppose the title of this one conveys the bulk of the purpose here. I'm a fan of vinegar. There's a lot of information out there about the healthful benefits vinegar can have on the body. Which is great, especially since it tastes good and there's a ton of things you can do with it.
I also think there are nights when a shot of vinegar mixed with some water can do wonders for the following morning. If you had too much to drink and there's a hangover on the horizon this isn't going to change that. But if it's getting late and you feel like a minor version of such a thing could be in store...reach for the vinegar (again, provided you like the taste of it).
I use Bragg's Cider Vinegar. It's awesome and usually there's no substitute. I say usually only because it's apple season now and local orchards that sell cider will often sell homemade unpasteurized vinegar too.
I realize the drink below has alcohol in it which kind of contradicts the whole point of this post. Both of the ingredients however are pretty low in alcohol content. I see this one more as a last-drink-of-the-evening which also manages to sneak in something a little bit healthy.
