One other thing you might try that helped me heal. The dietician put me on Zinc Sulphate (which is supposed to improve taste and promote healing), 500mg of Vitamin C twice a day and multivitamin like Centrum. I had most of my taste back at 6 months, had to eat by mouth because never had a peg, and had gone back to work full time 3 weeks after radiation was done, way too soon but I did it. Check with your doctor before trying any supplements, but it might be worth a try.

Take care,
Eileen
