Hi FionaM13,
I just want to let you know that I will probably be put onTamoxifen also after my double mastectomy next week, so I've been researching and then I asked my cousin, as she was on it, she told me she had NO sides!!
I think if you haven't been through menopause perhaps its worse because it probably gives you menapause symptoms I guess, but she said she did LOTS of exercise and ate healthy, she felt ok.
Just thought I'd let you know, hope this helps. Good luck.
Sending hugs, I know it must be stressful.
