I started noticing changes at 43. First symptom was insomnia. Then when winter rolled around I was hot at night and did not need to use my heating blanket. I wore my summer PJ's all winter and it was a long cold winter. Anxiety, emotional, change in my periods, forgetful.
I'm still struggling with getting better sleep. Some of it is early morning anxiety and some of it is I'm too hot. Then when I turn on my fan I get too cold. Then I get warm again. Back and forth all night.
