This topic is very much connected to the one on menopause and the one on mental illness -- American women are being over medicated and adding estrogen to your system is not a good idea. Everyone should read "What your Doctor Didn't Tell You about Pre-menopause" and "What your Doctor Didn't Tell You about Menopause" -- both by Dr. John Lee. He has a web site if you want quick info. Estrogen dominance seems to be the root of many female problems -- I read somewhere too that only American women suffer from PMS. And estrogen is in the food and water, so it's easy to get too much. Right now I'm trying to get rid of fibroids. My mom had a mastectomy and blames ERT for it, that she was on for 30 years. I just convinced my daughter to get off the pill -- she's been on it for 10 years.
