Ditto. Before I sytarted using my PEG for most of my nutrition, in fact, I began to use ot for hydration because I had the same problem with water tasting funny. I too have potential problems with kidney stones(a CT scan of my liver that I had when I was diagnosed with oral cancer just happened to also show several LARGE stones--probably too large to pass through which can be a good thing but I don't plan on taking any chances) and so I need to be sure to get lots of water and other liquids. I put a lot of water and tea and occassionally juice and other sorts of liquids--through my PEG every single day.
