Letrozol

I've been on Letrozole for 6 years now and apart from joint pain in the very beginning I've not really had any problems. My oncologist says next year I should be able to stop taking it. I was 48 when I had cancer and probably perimenopausal but after chemotherapy they said I was post menopausal. I had no symptoms that I know of. My question is when I come off Letrozole will I be hit by menopause symptoms. Im a bit worried that all the horrible things I missed out on will come back.
