I'll agree with the others that it really depends. I'm watching a family member who would like to work be unable to focus for long enough to get much work done. I suspect in his case it is pain mixed with the chemo and fatigue which makes good work difficult. Right now this is in the first couple weeks of treatment, I'm trying to be optimistic but also prepared for this to continue as treatment does. But now I have something else to watch out for I guess.

Either way, best of luck.
