Chemo Brain

I'm three years post-treatment and having some issues with cognitive function.  I remember during chemotherapy that I lost track of time and space a bit.  I'd wake up not being awake of where or when I was and needing to orient myself often.  

These days I'm a bit better at it, but planning is hard, timetabling is hard, tracking things is hard and I cannot remember details or guarantee I'll be at an appointment no matter how good my intentions are.  I was never like this before BC.

I have been trying to use my phone to prompt me and having problems with not hearing it if the sound is too low or not having the phone close enough to me.

I'm wondering whether an Apple watch might be a good thing for me.  I don't know if they vibrate on reminders or not but maybe that could work. 

I'm at a point where I'm wondering if I'm fit for work any more.
