I did radiation and chemo also but I never had a feeding tube. Scrambled eggs and oatmeal became my friends. When I didn't feel like eating I drank Ensure, Boost, Special K Protein, Carnation Instant Breakfast and my husband made lots of shakes for me to keep my weight up. Sometimes I had to sit at the table for awhile to get enough food down but I did it. I was determined not to have to have the feeding tube. Just remember you WILL make it through and come out on the other side. Hang in there!
