Hi there-
I have PCOS and insulin resistance, too. I waited until I was completely finished breastfeeding before going back on Metformin. Too bad your doctor did not tell you about that. Anyway, don't eat too much fruit--fruit is good for you but also has lots of carbs in it. Eat more veggies and exercise. The exercise will jump start your metabolism and help you burn the calories you are eating. Also, you do not need that many extra calories to breastfeed, but it is hard to lose weight while you are nursing because your body won't let you, since it knows you are feeding another body. Good Luck!
