Caroline, Carol, Caro,
The weight will come off. It will. Don't focus on it.
And yes, I'd be the first to admit that I do easily accept counsel, or the well-meaning advice of colleagues (which is never well meaning, is it? It's always meant to bully, or put you in your place to make them feel better about themselves, more secure in their positions).
Moreover (you heard me), I dislike commentary about anyone else's body as much as I dislike someone picking on my own physical shortcomings. If you feel no one has applauded your mini-success, let me set you straight: you are awesome for quitting smoking. That's a huge accomplishment. One that will pay dividends as you try to get pregnant; the cravings will go away just as the weird ones arrive in the first trimester.
