things I tried....all the complementary and herbal things, including yam cream, except soy milk. To me soy milk tastes like pond water and I figured if my body hated it so much it couldn't need it. The yam cream might have worked or it might have been placebo.... I did try HRT but this was 25 years ago and there were less options. I refused premarin. anyway HRT turned me into a real throwing things harridan so that was a no go for me too. I gave up alcohol which didn't help, cut right down on sugar, also didn't help
Things that worked. Wearing and sleeping under all natural fibres, cotton, modal, tencel, linen. Reducing stress as far as possible. Using a cold water spray. Swearing.
Not to wee on your parade, but 'get through" how I laughed....I still get hot flushes and dizziness although not nearly so severe or so frequent as they were at their height. They are like old friends....
If its only hot flushes, I believe there is a non hormonal treatment for them now.
