I haven't had a period for a year. I am 47 so relatively young for menopause but hormone levels indicate that's what it is. I have had no hot flashes, mood swings etc. At first I wasn't too sad to be passing into this phase as I was happy to be no longer having periods and seemed, at first, to have got off lightly 
However... what I do have is total brain fog, low energy levels and an on going sense of not quite keeping it together. I used to be very efficient but it's taking a lot more out of me now to keep on top of things. I also have no sex drive ...
Could this all be due to menopause ? Otherwise I am very fit , in good health not depressed etc.
Has anyone else suffered these symptoms and seen an improvement after taking HRT ?
