I have Bile Duct Cancer which spread to my liver. I did a year of chemotherapy and am on immunotherapy currently. My treatment team has me drinking 2 quarts of water a day to keep my kidneys working and flushing out dead cancer cells and the toxic chemo drugs. I like to add lemon juice. It's not easy to drink that much water and it requires a lot of peeing but I remain fairly healthy and it's part of my treatment. A positive attitude is proven to help along with a Spiritual Connection with a Higher Power. I stay socially involved with other patients on this forum and their treatments- working, not working, side effects etc. I have my bad days emotionally too, especially before and after treatment and before doctor visits. I am thankful for treatment that is working. John
