Low dose tamoxifen

I had a review with my breast surgeon yesterday and had a good discussion about Tamoxifen side effects and taking a lower dose.  He is very compassionate and agreed with me that quality of life has to be one of the priorities in my life.  I simply cannot tolerate even a half dose (10 mg).  My muscles are still and aching and my joints and ligaments hurt 24/7.  With my doctor's blessing, I will from today take 5 mg daily and hope that I can stay on that for the next 4 years.  I know that this increases my risk of a recurrency to some degree, but I have to live with that.  I will have yearly mammograms and six monthly check ups and I will try to live as full a life as I can and not worry about the future too much.  I feel better now that I have made this decision wlhich was not easy.
Best wishes.
