I, too, experience the weird cravings, and for me, it's salts. I also have hypertension, and salt is a no-no, but for some reason, I get hit with a craving for something salty, especially potato chips or popcorn. I fight the craving, but sometimes I get weak and give in, and like clock work, I get sick. I don't know why it's salt, though. Anyone have an idea?
