Bloop,
As much of a proponent for the PEG as I am, I think that at week 5 and needing a replacement, I would request the NG tube (and only if you begin to be unable to swallow) instead of dealing with another insertion into the belly. Your body is so stressed and depleted at this point, I would be leary of another procedure that required healing to the degree that a PEG requires.

JMHO, Deb
