You’ll be so happy to be done with that chemo and your body will too! Eventually your taste buds will return, the nausea will subside and hopefully that nasty taste is history for you (along with the cancer!)
I remember it took my intestinal tract a little while to settle down into a ‘normal rhythm’ after getting off the anti-nausea meds. They helped immeasurable to keep food down but they also tend to slow down the peristaltic movement of our guts.
Have you tried any Xlimelts or Biotene products for your dry mouth?
