I was Googling about cycle issues and found this- which I had never seen before. I thought it may be helpful for others as well.
This is the URL for reference.

Thank you! Thank you! This makes so much sense to me! I guess at 40 I didn't realise that I was almost menopausal - but the explanation (and the symptoms!) outlined here explain everything perfectly!

Thanks for posting!

I'm glad it helped. I too felt better after reading it.
