I wish that HRT was the magic solution for me, just as many of you have posted. I have been on HRT for almost 5 years and my doctor has tried various permutations, but it has made no difference to me at all. As a result of the menopause, I have been diagnosed with sleep apnoea (which apparently is commonly brought on by the menopause), and my sleep is broken / fitful / light like TerriBull. The medics can't offer me any treatment for the apnoea other than a machine and badly fitting masks that I've had to give up on as they made my sleep even worse. Every time that I moved an inch, the mask would leak and wake both myself and my DH. I tried mask liners without success. I became afraid to sleep, knowing that I would be woken up quickly and noisily. I still get hot flushes most nights, and have also been suffering with night frights during these years. Most weeks I have at least one awful nightmare / dream - and I have murdered my friends and family in so many gruesome ways that I can't count. I would love to sleep like a baby, but I feel that those days are but a distant memory as my Mom is almost 80 and still suffering with flushes that are worse than mine.
I took early retirement as I couldn't concentrate, and was having to book meeting rooms to have a nap during my lunch break, just to cope. At least during retirement I can stay in bed longer and try to get more sleep.
