I have all those even down to the heart murmur! Wow!
I had to be on prescription D -- I was that low. My current list is thyroid med, metformin, multivitamin, fish oil, extra D, B12, cal-mag, inositol.
I don't know anything about IP. This spring I took the PCOS Diva Jumpstart class online though and that helped reorganize my food.
I feel good on a 40-30-30 type plan. Definitely protein + produce, go easy on the grains. Having new recipes helps. I was in a rut.
Maybe that helps you as you form your plan?
Hang in there!
