I started on Tamoxifen almost a month ago,and so far it's been great!I have been having hot flushes before this,but they are definitely no worse.Very bearable.I asked my oncologist if Tamoxifen itself,will put on weight,and her take on things,was more that if it made you feel tired,because of hot flushes,lack of sleep etc, well then you would be less inclined to exercise,or keep up with what you had been doing beforehand.I weigh exactly what I did the day I was diagnosed with BC.As always,it is proven,that exercise helps, with any side effects of hormonal therapy.I walk or ride every morning,and then at night after dinner,sometimes as late as 8.30 pm I run and walk.(you might call it shuffling!) I have always been very conscious of my health and my weight,and for me, having BC has motivated me even more to take BETTER care of myself.I am seeing an exercise physiologist tomorrow to learn about the very best exercise that we can be doing after treatment.I will put on my blog tomorrow night what I learn,if you want to take a look.Just one more thing with Tamoxifen,I take it immediately before I eat dinner,and I take it with a large glass of water.I set an alarm in my phone ,cause it is so easy to forget it.Hope,that this might help a bit.All the best.Robyn xoxo
