Hi I came across this forum searching for an answer I am on day two of a liquid fast. And I have this terrible craving for vinegar. 2 a.m. I wanted to go drink the juice to the pickled beets. I could actually buy some vinegar and drink it. Does any1 know why my body would be craving such a thing is there soomething in it that my body wants. Just curious or could it just be a flook that i'm having such a craving?
