I would just try to eat a little healthier but I understand where you are ocming from completely. I was about the same weight gain when pregnant at the same time. I did gain a LOT towards the end and when all was said and done gained 62 pounds--I was very thin to begin with as well and tall so could carry it ok. The doctor did tell me it was too much but honestly, you can't jsut start dieting and the weirdest thing of all was I threw up my ENTIRE pregnancy--I shudder to think what I would have gained had I not. I will add and not sure if it has any bearing but my baby was a boy and was big at birth and I wonder if that has something to do with it as well. The good news is that at two weeks post partum I was down almost thirty pountds and now five weeks after his birth am down about 45.....
