I am also 25lbs overweight, prior to pregnancy I was 185, and at my last check-up I was at 178. It's the lightest i've been since I was 13. I never had morning sickness per say; i never threw up, but I did have alot of food aversions... i could only eat oatmeal, cereal, yogurt and baked potatoes the first 3 months... i also caught 2 colds and was in bed, barely eating. I have my 16 week check up on monday, and i'm pretty sure i only gained a lb or 2 of it back. I don't really have any aversions anymore (except to chocolate which is weird) but my appetite isn't what it was prior to pregnancy.
