I have been on Tamoxifen now for three months and apart from changing the time of taking it from evening to morning, I have no issues that are a problem. Like Robyn, I exercise everyday and eat plenty of veg. I do get the odd hot flush but nothing I have googled, and believe me I think I have read the good , the bad and the ugly, frightens me more than not stopping the estrogen effect. At the end of the day we all make a personal choice on this my my experience is positive.
Stay well
Regards
Julie
