Wow......thank you all for your helpful responses. Karen I had completely forgotten about the Estrogen issue. Its been a few years since I've dealt with it. I was on Bio-identical for about 3yrs. I highly recommend this route for anyone who is having a difficult menopause. I am also very careful about my diet, don't use makeup, perfumes, & I now make my own laundry det. I do lots of my own home made cleaners etc. Still our air is so polluted, we can't seem to escape toxins anymore. I am off now to do some reading.
