Robin,
I just wanted to weigh in with my two cents...After I was done with chemo, I had my ovaries removed (had the rest of the plumbing taken out earlier) because my cancer was estrogen-receptor positive. Instant menopause!

My docs have recommended *against* black cohosh, primrose oil, and other phytoestrogens because they're not sure how they would affect the estrogen-receptor positive cells if any are left.

I also went through the hot flashes and mood swings. The hot flashes lasted about a year, then started becoming much less frequent. Between the chemo-brain and menopausal mood swings, I'm still on anti-depressants and mood stabilizers. I see a psychiatrist to manage those meds; a good psych doc is much better informed about psych meds than your average family practicioner.

Hope this info is of use to you - good luck with your docs.
