I too suffer from PCOS and it is dreadful isn't it!
I am having the best results having cut out all processed sugar foods, biscuits cake etc, fruit juice, sauces etc etc and it has opened my eyes a lot. Fruit and milk ae still great to eat and stil get my rid of sugar from fruits and vegetables and have also gotten my taste back! I also drastically reduced the carbs in my diet that don't come from vegetables, I still eat sandwiches etc but not lots of cakes and biscuits etc it goes hand in hand with thsugar rung really.
The other thing that helped me a few years ago before I had my daughter (i was lucky in that it trigger my fertility enouh to conceive also) was diabex or metformin. I would really like the met again but haunt got around to hitting the docs yet!
Cutting out the sugar isn't easy, it' involves mood swings, bad sugar cravings etc in the first week or so but after that your body adjusts and you don't even miss it.
I really hope this can be helpful to you, PCOS really doesntmake it easy. I had a 20kg weight loss goal and I am about half way.
What advice has the doc given you? I know they can be rather dismal with helping
Good luck I hope to hear from you
