A few practical suggestions on the radiation treatment. The vomiting from having it applied to my abdomen persisted for 4 to 6 hours commencing about 30 minutes after the treatment. Eat a good meal that is fully digested before you go for the treatment. No sense in adding to the material that will be ejected. At 1200 rads, the diarrhea sets in. I found Compazine was helpful for the nausea. My treated area extended from sternum to pubic bone with the spine/pelvis getting some major hits. As such, a blood draw was done before each radiation treatment to make sure I hadn't dropped below a safe threshold due to bone marrow damage. My physical vitality was impacted for 2 years after the treatment. I could speed skate for 7 hours a day before the treatment and could not complete a single circuit of a skating rink floor afterwards. Two years later, I was able to mow the lawn again. Be patient. You will have no energy. If you need to vomit after a treatment, do it. Get the toxic crap out of your stomach. Holding it back is no virtue. It needs to go.
My experience dates back to 1985. The treatment was successful. The road back was slow. The only thing more wearing than the treatment is having people ask you how your are feeling over and over. Be a good sport and provide a single point of contact for your wife so she doesn't have to endure constantly recounting the experience to a crowd of well meaning friends and family.
