Cheri,
my husband worked on radiation (but not chemo) days until the last week. He took that off, and half a week following treatment. I drove him when he was on narcotic pain killers. He HATED that ... and went off them cold turkey the week after treatment. He is stubborn.
He had to sleep a lot longer than normally during and after treatment. Our schedule included me calling him at work to remind (nag) him to drink his afternoon Ensure.
He was lucky in that the Cetuximab chemo did not knock him for too bad of a loop, although it did give him a pretty good rash.
I think that walking our old dog everyday helped - got us out, and it was something normal.
Best wishes to you both,
Maria
