I can appreciate your reluctance to get a PEG. But consider that you are doing 40 treatments. That's a lot. I also believe that they put the tube in through your mouth, which if constricted, can create some difficulties.

One of the chief difficulties people have with chemo/radiation is dehydration. This can put you in the hospital. Although you may be able to eat, you may not be taking in enough fluids. The PEG will help prevent this problem.

There are more informed people than me on this list, so I will defer to the opinion.
