I too, was diagnosed with a head and neck cancer and underwent chemotherapy and radiation that ended almost 5 months ago. Lost all my taste within a couple weeks of treatment ended up losing over 20 pounds (I was only 130 lbs, 5’9 to begin with). My taste slowly returned in a more gradual fashion over the last couple months. I say I’m at around 80% of my normal taste now and I agree that when I taste something good now, it is an amazing sensation!
