Surgical induced menopause and hot flushes

Hi All, I had a lumpectomy in March followed by radiation therapy. At 53 I still had fully functioning ovaries with no signs of menopause so I had the choice of medical or surgical induction of menopause. I choose surgical as I'm one of those people who manages to suffer the side effects of all drugs. Since having my ovaries and fallopian tubes removed in June the hot flushes have hit with vengeance. I am having over 20-30/day & night and they are not settling down. My medical oncologist gave me a variety of options including magnesium at night, Clonidine, Efexor, Gasapentin, acupuncture, & CBT. Magnesium has made no difference, most of the medications are not suitable for me due to side effects. I am starting Japanese acupuncture tomorrow and using CBT techniques. I am walking gradually 15min 3 times a day (my back decided to pack it in thus the slow pace).

Any other suggestions that will help settle down the number of hot flushes I'm having?????
