I had this in 2001 when I had a very bad bout of the flu. Toward the end, food started to taste like sand. There were really no other symptoms, though that was bad enough. Went to the doc and he asked if I had HIV (answer: no). He said he'd never seen it in a healthy person. He gave me some lozenges that were almost worse than the original problem. About 3-4 weeks later it was mostly gone. It minorly flared up in the years after that, if I had a cold and skipped brushing my teeth.
