I was about 54yrs when I started to become extremely emotional(off the charts for me), night sweats followed. I had a mild case of it as I have talked with other women who had hot flashes that would happen at anytime during the day or night, where you become flushed with a warm or hot feeling and your face turns red, usually. andthen break out in a sweat. I understand it happens about the same age as our mother's did. It lasted for a couple of months for me, I think everyone is different in how long it last's.
My mom passed away when she was 56yrs old and never had a conversation about menopause so I had to endure it without knowing that much about it. Hope this helps.
warm thoughts.
