Craving vinegar?!

Tanna • Wife, Mom of 3, LDS
I crave vinegar all the time! I had at least five helpings of Olive Garden's salad the other day and now I'm scarfing down salt & vinegar chips! Anyone else have this craving? Why vinegar?? I wonder if it has anything to do with the gender of the baby? We don't know what we're having yet!
