I have spent the last 2 months having night sweats almost every night and it's driving me nuts.

I am 44 and have my womb and part of one ovary left after surgery. I've seen the doc who agrees I am peri-menopausal and prescribed HRT.
So far this hasn't made much difference but as I also have Multiple Sclerosis I am no doubt being more impatient than most people as I need to sleep well to cope with all the other stuff!
Before I started HRT bloods were taken and they all came back normal! FSH was 6. Now I am really confused as a lot of people say that the tests don't tell the whole story!
Any ideas, advice, greatly appreciated.
