Hi Carol, There's no reason for you not to continue taking the progesterone.  It is probably helping your sleep improve.  Many doctors start their patients on estrogen right after surgery, because now that you have no ovaries you have lost your major supply source.  Unless you have had breast cancer or have a significant family history (mother or sisters), you need to be on estrogen for long term health maintenance.  Estrogen has a number of very positive effects on the body, including promoting bone growth, protecting the heart, reducing colon cancer, maintaining vaginal and bladder health as well as managing many of the symptoms of menopause like hot flashes.  We know, from the most current research, that women who start on hormone therapy either before their last period or within a few years after menopause have better long term morbidity and mortality because we're healthier with our hormones; these women have less heart disease; and they do not have a significant rise in the occurrence of breast cancer.  So, the long and short of it is, you don't need to suffer the hot flashes you've been warned about, or the general aging decline that will happen without your hormones.  If your current provider is not willing to work with you on this, shop around for one who is up to date on the menopause research and knowledgeable about the use of bioidentical hormones. Good luck to you, Carol, Sandy
