Fatigue, it's a difficult one to diagnose. I was diagnosed with IDC breast cancer in 2019 and my surgery, chemo and radiotherapy was in 2020. I am now on Anastrazole. My problem is fatigue, it's different to tiredness . I find I am active in the morning but by early afternoon I'm wiped out and could easily fall asleep. I try to not have a nap but even so suffer from insomnia. Doctors advised trying Tamoxifen but Im wary of the side effects. I have had some more blood tests so maybe there's a reason.  Waiting for results.  Also the worry of cancer returning and my age 69 also a factor. Just so annoying  that I can't do as much. Im still working, part time gardening, walking but days like today my energy levels are nil. It seems trivial when lots of you are facing cancer diagnosis and various treatments but just wondered if anyone else has similar symptons.
