Hi Susie
I did the 12 weeks first also which they also thought would be good for my stage3 her2. I had a pet scan around 10 weeks and all the cancer was gone in the scan.
I did continue to go out and take the kids to school throughout all my chemo when I felt up to it, lots of hand sanitiser and getting to the shops early when it was quiet, I didn’t get sick once.
I did get diarrhoea too which I just used Imodium for and small bland meals
Having it every week was hard but I soon got into a routine and it was manageable
I work from home so I continued to do that with the odd lunchtime nap here and there
