PCOS and metformin.

Hi all. My partner and I have been ttc for almost 2 years now. I was diagnosed with PCOS last year and was just told to lose a little weight and stop smoking. I have recently gone back to my gp rather then the specialist and he has put me on metformin. I would love to hear some success stories as I am feeling so low and negative at the moment and need some positive vibes please :) xxx
