Mtx won't cause menopause but ctx often does. That contributed to a lot of my sweats, too.
I was told that Mtx does cause menopause!
I did not read that book, but would like to. I have seen/heard interviews of the author, Sherman Alexie, and best of all so far, I have a copy of the movie Smoke Signals, which I believe is based on one of the stories in that book (if in fact it is a book of stories?). In any case, Smoke Signals is one of my favorite movies!
