My RO would not start treatment without the PEG tube. I am so thankful I had it. I had a rougher time than most with the stupid treatments. Had to take a break after week three, because my throat was so bad it had swollen almost completely shut and could barely breathe. Then I was in the hospital for a few days. Not everyone has the side-effects, I think I had a rougher time during treatment, but healed up rather quickly after treatment. I quit using my PEg just 2 months after treatment. I would do what you want to do or what you are comfortable with.
