I got rid of mine three years ago when I had a recurrence. It's not so bad, though the last step into total menopause was a doozy. Mind you I had the op two weeks before chemo started, so everything was all fucked up anyway.
Like Karenj I didn't want to faff about with zolodex before AI treatment while my ovaries wound down on their own and since my cancer is hormone hungry, it was a sensible thing to do.
I've adjusted to the instant old woman thing. Id have prefered not to, but needs must and it's one less thing to worry about.
