About a month ago my taste seem to be fading slightly. After a couple of weeks I was overwhelmed with an internal smell that is so strong it covers up my natural taste. I've been to a dentist, my family physician, and an ENT specialist. Nobody can smell this but me!  The sensation is nasty, an odor similar to taking the lid off a trash can and getting a whiff that smells like sniffing a Sharpie, a permanent marker. I can't describe it accurately but it smells like a basement that is full of mold. I'm getting a CT scan tomorrow to see if the doctors can detect a cause.  It is really destroying my quality of life.
