Just a quick update everyone. I have now been on Tamoxifen for 3 years (wow, that's gone fast!!) and I am still going well. I am playing beach volleyball each week and try to go for 3 runs each week too. As I previously mentioned, the only side affect that I get from the Tamoxifen is night sweats and hot flushes (although these could be due to the chemo and I may have had them regardless of the Tamoxifen from what i have read).
Stay healthy and think positive...it makes such a difference to your quality of life :)
