Eating disorder?

I think I may have a borderline case of pica. My pregnancy has been marked by craving after craving for condiments and other edibles which barely count as food. It started when I was about 14 weeks along and thought I wanted a hamburger, only to discover that what I really wanted was just the ketchup, mustard and pickle. I confess to eating spoonfuls of mustard or mayo from time to time, when no one's around to see.

Lately I've been all about vinegar. Not the fancy balsamic kind that they serve you in restaurants to dip your bread in, just your average, run-of-the-mill white vinegar. The kind my grandmother used to clean the house with. I drizzle a little on my toast in the morning, mix a little in with my rice at lunch, drown my salad in it at dinner and bathe some croutons in it for a bedtime snack. I've eaten vinegar with avocado, turkey, fried fish fillets, and steamed vegetables. I cannot get enough of it.

Other not-quite-foods that I've been craving: limes, horseradish, olive oil and garlic. At least I'm meeting my fruit quota with all the limes I've been sucking on. Does garlic count as a vegetable?
