Thank you, everyone, for your thoughtful, peaceful comments.
My cousin (doctor) suggested that a PEG tube is a better option for Joe because he feels that the nose tube is actually irritating his throat. Joe is going back to the doctor's today for another consult. He is continuing to lose weight and I don't think he is properly hydrated, so I am hoping that he chooses to get the PEG. His wife is dead-set against it - I don't know why - but my guess is that he will go for the PEG. It seems to be taking too long to get the food/water in through the nose tube.
Thanks again,
Jean
