Busy times! Good on you for getting through the bulk of it. I may be reading your post incorrectly, but did you have a clip inserted in your brain?
Which chemo protocol are you starting? I had TCHP and didn't cold cap for my hair, but you might want to consider it because the docetaxel (the "T - taxel" in the TCHP) can cause alopecia. My hair is growing back now, but is a bit thinner on top - not sure yet if it will fully thicken up, although the thinning could also be caused by the anti-hormone treatment I am on though.
Sounds a bit weird, but once I was stuck sitting quietly in the chemo chair, I could just chill out and it was a nice change from the craziness of tests, appointments etc.
