Yesterday, I gave in to my odd craving for a Blizzard with Butterfinger in it. Turned out that was lunch. And at 2pm, I really wanted to eat my Bar-B-Q chips I'd brought from home. This was not a good combination. Then I got itchy for no apparent reason and became so amazingly uncomfortable that I went home at 3pm. A bath and a 2 hour nap fixed me up well. The amazing thing was that I was ready for bed again at 9pm.
So the lesson from yesterday is not to necessarily give in to odd pregnancy cravings one after the other.
