Brian,
I totally agree that keeping up with nutrition and liquids can make a difference. I'm not sure why my husband didn't get the PEG tube. Maybe it was psychological in that he thought he could stay in control of his body or maybe it was ignorance of how bad things could get. (I think it was more ignorance. Starting out we didn't know what hit us.) In my previous post, I was just trying to illustrate our own experience. But I'll admit, knowing what we know now, I'm sure he would have opted for a PEG tube. I'm positive it would have made a difference in his weight loss.
