Ditching the 5-year sentence of hormonal therapy?

Realy interesting subject a lady in my support group who has been with us and on tamoxifen was a mess. I didnt tealise till she came of it and the transformation over a short time was unbelieviable but recently her cancer returned.and she questioned was it because she stopped? Who knows she said regardless she still would have stopped it to feel ok again.many of us have not many issues re the meds, others of us suffer who knows whats the go.tricky isnt it. Adean xx
