The hot flashes at night were very bothersome. It got to the point where I was going to invent a refigerated bed! But ... I finally found the best solution. When I made my bed I used a wool blanket on one side and nothing but a sheet and a thin cotton blanket on the other side, so when I got hot I could just roll over to the cool side , and when it passed and I was cold I could just roll back to the other "warm" side.
I think the random day time heat waves were more tolorable , but I refered to them a my "personal summer"!
The idea of hormone replacement therapy was just way too scary so much conflicting data, so I opted for the method that was to me the most natural.... no presciption anything. I do take a vitamin with extra calcium but that more for the bone issues associated.
