Dear Mike - My son did not have Chemo nor a food tube, but he did have several weeks of radiation and he found that diluting some of the liquids with water helped him. Everyone is different, tho' and it seems to be a try and see what helps kind of thing. He did get his nausea med changed because the one he had no longer helped. Lots of people here have had experience with feeding tubes and chemo and I'm sure you will be hearing from them soon. You can also do a search (see top of this page) and get lots of information that way, too. Hope things get better for you soon.
