I had a similar experience. I didn't have a PEG either, and wound up in hospital twice in the last two weeks of rad. As sick as I was at that point, they wheeled my bed downstairs each day, gave me my rad, and wheeled me back to my room.

My RO was really adamant about not interupting my Rad. Early on in treatment the machine that I was assigned for treatment broke down. The day was busy, and everyone had full schedules. He had me shuttled back and forth between three other machines until they were able to fit me in two hours later.

In retrospect, as much as I would have loved a break towards the end, I don't think it would have made much difference in the way I felt at that point. It would have just delayed the 'graduation day' ceremonies. My radiation techs have a tradition...a cupcake with a candle after your last rad treatment. For me, it was a can of Ensure with a candle...my throat and mouth were WAAY too sore to swallow cupcakes!
