I had my PEG from mid-treatment until about 8 weeks after treatment. Food wasn't great at that time, but manageable. I gagged not only with food, but also every time I yawned-I don't know if that is common or not. Some days the pain meds would make it worst, other days it didn't seem to matter. As many others have said, it is important that he feels comfortable eating, especially from a psychological standpoint which can be the hardest, before the tube is removed.
