Valerie, I had the same sensation (kind of a dryness but it also felt like something was stuck) that triggered my gag reflex a lot during the end of my treatment and (here and there, though it got less common) for months after. Has he been given any kind of "magic mouthwash" that he can swallow? I found that often helped get rid of that feeling.

I managed to do tube feeding anyway by basically trying to pour something down the tube whenever I wasn't feeling like I was gagging. Sometimes it came back up, but I got enough down to get some calories. He has to keep trying to do the same.

By the way, this is gross but needs to be said--if he has a full stomach and the gags turn into stomach heaves, if he uncaps the tube and puts it in a bowl the stuff in his stomach will come out that way and he will vomit less through his (probably sore) throat and mouth. The Peg tube works two ways!
