hi Joe,
it is doable, lots of folks have done it
i did my rad/chemo away out of town and stayed in housing offered by the hospital for cancer folks... it was an appartment with private rooms/baths and group eating area. a really good feature is that it was just 1 bock from the cancer center so it was very easy on transportation. i also learned quite a bit from the folks who came from lots of interesting places... and who were doing everything they could to kick their cancer.
one difficult thing for me was keeping up with the schedule and recalling all that the docs told me. fortunately my wife came to those doc visits and kept me doing right... i think caregivers do us wonders. see if you can get a volunteer caregiver to help you out or ask the docs if you can record your visits.
all was new to me, so networking helped greatly. Joanna is quite right in that this forum has great folks who give excellent careing advice... so really do what you can to stay connected... and ask questions about anything/everything that concerns you.
you are not alone.
cu,
