Good morning aej1954, I'm about to turn 78 years old. I'm on my 5th year of AIs. I started with some of the ones you've mentioned here after my lumpectomy, with all the intolerable side effects you've mentioned here. Finally I was put on Tamoxifen and that has been MUCH better. There are side effects, but tolerable ones unlike the ones I first tried. December will be my last month after 5 years of AIs. (Hopefully!) I wish you the best of luck with your decision and if you do try Tamoxifen, I hope you find that it is tolerable for you.
