When I was pregnant, I was sick for the first 5 months. Wasn't just in the morning, either: and it was hard to predict what would set me off.
Doctor was yelling at me because I was LOOSING weight.
I craved egg-drop soup, bagels and lox, and tuna sandwiches.
Eventually the sickness stopped, and the doctor yelled because I put on too much weight, too fast.
Blech. My best friend in Oklahoma gets horribly sick for months, too. Very difficult. I don't think we'd have all these kids if I was really sick in pregnancy!
