Several years before I got cancer, I became very ill. I had been sick for a few days and was getting worse so my friend insisted he take me to the ER. My fever was 105 and I could barely walk. After days of testing the docs finally found out what caused me to be so ill. I was severely dehydrated due to not drinking enough water. I had a bladder infection which went unnoticed and it turned into a kidney infection which was trying to shut down my kidneys. I was told if I hadnt gone to the ER when I did, I probably would have died in my sleep that night. I still remember having several conversations with doctors and nurses about how much water to drink per day. This was years before cancer and I loved to drink my coffee, iced tea and coke. That was about all I ever drank. If nothing else, from this experience I learned that every single person needs water to drink every day even if they are getting fluids from other liquids. I had always thought I got water from the other beverages I drank but I learned that you still need plain old water too. How much? ..... thats another questions that greatly varies.

Even with taking 6 cans of formula every patient still should be drinking a few water bottles a day. This is especially important to flush chemo out of a patients body. Also if a patient has any kidney issues extra water is a necessity while going thru treatments.

Bottom line.... when in doubt check with the doc, the nurses and/or a dietician. By asking each one you can see how different their answers are.
