Like you, I'm not going anywhere near anything with oestrogen in it. I'm doing hot flushes cold turkey. Won't even have soy so no more salt and pepper tofu from the local takeaway.
My hints are to wear cotton and avoid synthetic fabrics that don't breathe. Keep cool water on hand as I find that hitting my stomach with cold water at the same time I'm having a flush makes it more bearable. I have an eau de toilette handy. It might be just psychological but if feels better if I spray during or after a flush.
Good luck. I've been on Tamoxifen since February and I think the hot flushes are getting fewer.
Helen.
