Hi Ess, does he have a pump with the PEG? This helped my brother's nausea. Another thing. If he's on any pain meds, be proactive and prevent constipation which is one problem he doesn't need at the moment. My brother says that meds-induced constipation was the very worst of the the whole thing, even though he also had a bad reaction (but probably just normal) to the Erbitux. Get him to drink lots and lots of water. Simon mixed each can of PEG food with 50% H20, and drank more besides. Helped him through, though didn't prevent the constipation. When you in the middle of it, it seems neverending - you get to the end of it, you blink and it's 6 months in the past. I wish you the very best.
