I quit smoking for both my pregnancies. Did not affect my weight gain during those pregnancies at ALL. Oh, and I didn't expect applause for quitting for pregnancy, either; that was like a basic requirement of being pregnant, ffs. That's like asking for props because you stopped beating yourself in the stomach while pregnant. You're not supposed to beat yourself in the stomach, and you're not supposed to smoke or drink while pregnant. You didn't do something special, you did something you're supposed to do. (In fairness, smoking does raise the metabolism and when you quit, some people can/do start burning fewer calories so need to take in fewer to maintain weight. But we're talking about a small difference here for most people, and one that doesn't affect some people at all. It's just that it's not all oral fixation/substitute for something to do with mouth & hands. We know that's not the case with this fat piece of shit, either way.)
