Medications, more medications, one day at a time. I can't stress enough staying the course - people who don't complete their treatment have very poor survival rates.

They also always told me to not have treatment on an empty stomach as well. All ionizing radiation is tough - doesn't matter whether it's IMRT, XRT or Tomotherapy, but it normally doesn't make you sick (the adjunctive chemo, well that's another matter). Talk to the RO and the MO and see what solutions they can offer you to mamage this. You have to get through it.
