No no no to Gatorade! It contains high levels of sugar which promote cancer growth. You need to completely cut out sugar if you want to win this war. I drink Nectar hydration packets (available on Amazon) in my water once per day & I get IV hydration twice per week to stay hydrated. The Nectar packets are the best tasting & do not contain ‘natural flavors’ which is another big no no. Most things processed contain these so called natural flavors which are chemicals put into the food to make them taste natural or better? If you have a poor appetite, I would highly recommend trying Rick Simpson CBD oil. Lack of appetite will also make you dehydrated. The CBD oil helps me a lot with my appetite. It helps me get to sleep & it also helps with nausea & anxiety. Hope this helps somewhat. Best of luck on your journey!
