I'm on bio identical hormones and have no problem. My doctor/gyno is a very respected expert in the field and she doesn't believe that even after menopause women should be without hormones. She believes that all women should take them and just because nature has taken it's course or you've had a hysterectomy that you should be without them because hormones effect every part of your body. If you google Integrative a Medical Group of Irvine, I think you will be able to read a part of the book she is writing on "Menopause Mastery".
