Billy, plese read the content information on your Propel water label and compare it to Pedialyte and Gatoraide. These two are proven to help with dehydration-I don't know what the Propel benefits are, but it may have stuff in it that you don't need to deal with. Juices DO NOT take the place of water-unless you mix them with water- ask the Rad or chemo nurses to break down for you the amount of and what kind of fluids they need yu to take in daily and write that down. Ask what kind of I.V. you would get, if you went into the E.R. for dehydration. Knowledge is power in this fight.
By the way, while soups provide variety, it is very hard to get very many calories with most soups unless you load them with whole milk, cream, butter, cheese, etc. Can you tolerate V-8 or tomato juice through the peg? You are sounding strong, Billy, keep it up! Amy in Oz
