I started my peri-menopause around age 37, and I still am, I'm 50. However, everyone will have their own unique experience. I have been told that if you watched your Mom go through it then you can bet you will have the same experience. I can say that it isnt true for me. My Mom had a horrible time of it. I am doing good. Got my first hot flash several weeks ago, lasted all of a couple of minutes. I have had mood swings and crying episodes but they go as fast as they come. I go with the flow of them now.
There are all kinds of websites that explain things better than me, and I have read that exercise, diet, and vitamins do help with the symptoms. I have also read that meditation and yoga help keep things balanced too.
I like to think of it as going through puberty again I am just wiser and more experienced. [laughing]
