One other thought....I had almost forgotten. My treatment plan was to have an IV flush the days following Chemo with a blend of various "things. I remember Potasium being in there with other "good" things. Not sure if this is Std Protocol at Duke or based on the Dr ?
Also they always had the nutritionist meet with me at least 3 times a week to grill me on food intake, fluids, taste issues, exercise, ideas on how to get a calories/protein . In truth she was very motivating and a big help Duke also had a Psych person vist with you frequently to help with the mental aspect of treatment, pain, frustration , etc. I am a half full kinda of person but it was nice to have someone to yell at, talk to etc. my point is use all of the resources they have...you are paying for them.
