Is this my wife? :)
I just finished with my first round of chemo and I have been really fatigued. It's been 4 weeks since I had my last chemo and I'm just starting to feel better. There were days that I would take morning and afternoon naps. She did drag me out of bed every so often to get out of the house which really felt good.
I would say from the husband perspective, I really did appreciate the times when she tried to come up with things and at the same time was respectful of my wishes to rest.
Good luck and best wishes on your husbands healing journey
