I didn't get any bad side effects when I had tamoxifen from 2002- 2007. All through my first lot of chemo in 2002 and the tamoxifen I never even missed a period! Thank goodness the chemo pushed me into menopause this time around, because I couldn't take the femara if it hadn't. I never thought I'd be happy to be in menopause at 44, but my priorities are all different nowadays! Like you, I went out today and forgot my hat! It's so damn hot in Perth isn't it? Good luck on the tamoxifen; I hope it all goes smoothly for you. xx Jane
