This is such an interesting thing. Maybe it's just us Texas girls, but I did the very same thing shortly after my surgery. I was totally craving pickle juice. It was the best thing ever. Then, I did a little googling and found that apparenlty lots of folks after WLS crave pickles. Weird, weird,weird.
I even ordered pickle pops...like the cheap popsicles that you freeze, but they are actually pickle juice. I haven't had them since then. But, boy did they hit the spot when I needed them!
