I often have to drive and must maintain sobriety. Lately I have been ordering an old-school bartender hangover remedy.
Club soda and bitters.
Sure, most of us order club soda to have a low-calorie non-alcoholic drink and yes bitters are mostly 45%ABV. A dash or two of bitters will add an interesting flavor to your soda and a very, very small (a dash) amount of alcohol. I like it. Any bitters should do the trick and even a wedge of lime can be nice. I imagine that this also is way healthier than a regular or diet soda.
