Hi Donna
I pretty much worked right through chemo, in hindsight there were probably days I was there when perhaps I shouldn't have been but it was good for me to maintain as much normality as I could, I have a great boss.....
I'm finished chemo now but I'm still finding the odd weird thing I did while still under the influence of chemo brain!!!
I've managed to avoid missing any appointments by putting them on my wall planner. I use a bit of a code because everyone who comes into my office can see it, but it's in my face enough that it's impossible to miss so I make it to the appointments.
Don't know if this is an option for you but it might be worth a try.
