Again, thanks for the input; that all makes sense. Regarding "better advice" or "better questions," it has been rather frustrating in that the RO's office seems pretty flaky/unorganized, and he really hasn't had any appt where he got to meet with the doc and discuss tx plan, options, etc. There was no talk of dental care, tx issues, length of tx, etc at all; almost all info we've gotten is from sites like these. He had his first rad last night and will go in again today but wasn't even on the schedule so had to call them first thing this a.m. to get on the schedule. No talk of pain meds or anything; kind of frustrating! The nurse did meet with us once early on and did state the tx would be hard, etc, but it seems like a 'flying by the seat of one's pants' kind of thing. When J asked about being able to postpone the PEG tube a bit, I wish they'd pointed out what a cpl of you just mentioned about the greater challenge of doing the procedure after rad's already started (or mucositis has developed); it was just "fine." That info makes a difference!
