It's very important to take your hormone blockers orders on them for five years and the doctor told me that if I hadn't been my recurrence after 10 years would've been a lot earlier . There's no point in taking them if you don't feel well ask you Dr about other options . I have change Tamoxifen and I'm now on exemestane which is working well for me . I hope you find something that works out well for you . It is your decision but really consider the long-term impact if you decide not to take all hormone blockers. Take care
