Hi Flutterby, sorry I can't come up with any alternative remedies but just wanted to say you have my sympathies. I had a decade+ of nightmarish symptoms before starting HRT well postmenopause & now back on it after a long break, though life is certainly better for it, getting way too hot at night seems to be one thing I just can't crack - 16 years on from first symptoms.
I take up a pile of refrigerated HWBs every night & leave by the bed until I start to overheat then pull one in. When that gets warm from my body heat I sling it out & use another. Also bought a 1-tog Duvet from Dunelm & never have more than a 2.5 tog on, even mid-Winter. Whatever the tog, I still end up doing the duvet hokey-cokey most nights. We keep the bedroom cool, sleep with windows open, use a big oscillating fan in summer & I have a large glass of cold water by the bed. I make sure to stay cool in the evening before I go up to bed too. Not through having too much of my own padding, as I'm underweight! It's a pain isn't it, as it wrecks sleep & that makes you feel rotten when it goes on long term.
I remember seeing my Mum flush when she was well into her late 60s. She was postmenopause at 46 & never took HRT. I think unfortunately for some of us it can just go on & on.
I'm sure you know some women find certain antidepressants help with vasomotor symptoms, but that may be something you prefer not to consider.
I do hope you manage to find some relief. Please let us know how you get on.
Hi Beaker, search facility often doesn't work for me either, so thanks for sharing how you get round it.
