I agree with PJ - I was told NO homeopathic drugs, no soy. Unfortunately we just have to learn to live with the hotflashes. Try sleeping in a tank with your hair up if possible - as the worst hot flashes come at night. Shower lukewarm - carry a bandana with you to wip away sweat and so you can wet it and use to cool off if needed.
Lunuesta I hear can still be addicting even tho some reports say it isn't. It also can wear out it's effectiveness. I've been through them all and none worked for me. My doc now has me on Trazadone - and it knocks me out ALL night. Someimes I find that I don't even roll over, I sleep so heavy. So always something to keep in mind if this one fails you later. Chemo for me caused horrid insomnia that I still battle 3 yrs later - Trazadone works miracles for me (but I'm sure it can carry risks of dependency as well).
Good luck with the hot flashes & sleep!
