You know what, the more I learn the less I want to know about all this. Really feeling for you, I had no idea tamoxifen was for 5 years. I must say Im not all that impressed with my onc and the way I have to come on here to learn this stuff@!! GGRRR
Back to you, it sounds ridiculous to go on HRT! Please let us know what your doc says about the stats of reducing your time on Tamoxifen. did you get those side effects pre tamoxifen? I get both night sweats and tears on my current chemo, dunno if I can do another 5 years of it! :-)
take care you xx
