I went through chemo for stage 4 cancer 14 years ago. After treatment was over I was not sleeping and was all over the place mentally. A year later I found a doctor that had my hormones tested. My hormone levels were zero. I had no hormones. I was prescribed compounded hormone therapy. It was a night and day difference. I was finally sleeping and starting to feel normal again. The chemo treatment put me into early menopause. So, I do and will continue to have my levels tested annually and will continue taking cBHT. I have tried going without them in the past and can tell the difference. My life and family's life wouldn't be the same if cBHT was not available.
