Linda,
After a couple of weeks of radiation I too lost my sense of taste and by the third week could barely swallow and got my PEG. I am one of the many here who is a big believer in the PEG tube and see nothing heroic or beneficial in foregoing the PEG. I never once had to go to MDACC for hydration or related problems. Since I kept a PEG for 10 months, I did change it out for a new one once.
I also got the 25mcg patch to start, but shortly thereafter moved up to a 50 and eventually 75. After treatment ended and the pain began to lessen, I moved back downward and eventually weaned myself from the patches.
Make it easy on yourself.
Danny G.
