If you get anxious about it, it will get 10 times worse.
I went through a period of about 3 months a few years back when I was really worried about my memory.
Went to GP and they asked me to recount all the times I had had ' memory loss' moments which
I was really worried about.
She then laughed and said - there you go, you're fine.
For me it has been just one of the unpleasant parts of the Peri journey. Two years on don't even think about it now.
I'm sure anxiety played a large part. I felt foggy at the time too.
I've never been on HRT.
