@mommabird74 Good morning. It is just after 5AM, and already up for almost an hour. But I was an "early bird" even as a youngster. Menopause, or perimenopause, or monthly fluctuations in hormone levels can all play into sleep disturbances. It will be interesting to see what your blood results show to you. Will you report back and let us know? I had a hysterectomy in January 1999, and never took any replacement hormones. That was my choice and my doctor's opinion.
