Thanks for all the responses. Here are answers to some of the questions:

I am being treated at St. Joseph Hospital in Kokomo, IN. They are a CCC center.

Yes, I do wear a wide brimmed hat and sun screen.

I am still able to eat some. I am watching my caloric and protein intakes to make sure I get at least 2500 calories and 50g of protein each day.

The doctors seem to think that Ensure will care me if I can get four to six of them down each day.

I only have fourteen more treatment days (I get the weekends off), so I am hopeful that I can continue without the PEG

My weight was 186 when I started treatment. I tried hard to gain weight the first week or two and got up to 194 but I am down to 190.
