At 53 I’m now on HT until I die. I’ve avoided it for two years re quality of life. I’ve been on it for four months but actually not too bad. Plenty of flushes but not excessive sweating going with it. Sorry you suffering so bad. Mine are mostly early morning but I sleep through the night and have a couple during the day. Many people on the forum say that sage tablets can be useful, or as above you may get used to it or adapt to it. Good luck.
