I started drinking pickle juice, which has a lot of vinegar, out of the jar last year. At first I thought I was doing that because I was too energy efficient (aka lazy) to cook (or to clean the fridge) while my wife was gone on a 5 month vacation to the Phillipines.
After I Googled “pickle juice” I learned that it hydrates, is a muscle relaxant, aids digestion and more. Seems like my craving was a self correcting reaction to working so many long hours. I drink it all the time now.
