Tami,
I think that your mother was unrealistic in her expectations. Most of us were totally disabled for a time. I was off work for almost 2 years.

It is not a good thing to not be able to complete treatment. Some here have had to take short breaks, but my oncologist tells me that completing treatment is vital to survival.

I was supposed to have 3 Cisplatin infusions and they shortened it to 2. I did have a very rapid response to the radiation and my medical team all agreed that I could get away with it. If they had told me it would have made a difference in my survival odds I would would have went ahead with it in spite of how ill I got.

It is a brutal treatment and many (including yours truly) suffered immensely (I am a year younger than your mother). I am fully recovered now and back to work.

The doctors need to do a better job at managing her side effects. Nausea can be caused by many different things so they need to do a process of elimination.
