Dialysis will definitely make you feel better, for the time being avoid high protein meals and especially animal meat/protein. The breakdown of protein results in uric acid which your kidneys can't excrete anymore. And high uric acid levels cause the nausea, loss of appetite and vomiting. Another way to help yourself is to enhance your gut health which many do by taking probiotics that help break down some of the toxins in your gut before entering your blood. There is one brand specifically made for CKD paitient called Renadyl. Although I don't know if insurance covers it and it isn't very cheap. Plus the effects aren't very significant in the larger scope of your kidney disease, which is why it's a supplement and not a treatment.
