Judith,
I was lucky enough to work for a company who donated vacation days to me for days I needed to be with my husband. During treatment I worked from home a lot. I also relied on my husbands family and my adult children to take him to treatment some days so that I could go into work.
I have a real control problem when it comes to his care so I was able to be with him most of the time.
There is really no set answer because everyday will change. Just buckle in and make sure you research the cancer and the drugs you husband is taking. cray
