@dragonfire just an anecdote here - my taste also disappeared but eventually came back. Shortly after my treatment a friend of mine came to visit and brought some expensive chocolates. When I took the first bite it was totally shocking - absolutely no sweet taste instead just the bitter chocolate, like taking a tsp. of powdered chocolate. Now the only thing I notice (20+ years later ) is having lost the ability to differentiate red wines and most hot pepper sauces are equally hot.
