Hi RuralRach, I’m not on HRT and have night sweats, they seem to come and go though. I have started doing 5 minutes box breathing (breath in, hold for 4 seconds, breath out hold 4 seconds - you can Google for better explanation! ) in bed, it may just be my imagination but it really seems to lessen the night sweats and the severity. I have noticed the difference when I haven’t done it, maybe worth a try.
