i am 53, have pcos and depite glumetza, progesterone, lexapro, and estrodial spay, i am exhausted! My thyroid blood work came back on the normal to low side (nodules were present on my thyroid) and I am waiting for cortisal saliva test results. I have always had problems falling asleep and still do. But once asleep, I sleep 12 hours and wake up exhausted. Any ideas?
