Sounds the same as me. It was gradual though. I first noticed when cleaning up after the dog, the **** didn't smell so bad! I also saw an ENT specialist who sent me for a MRI which proved nowt. The only suggestion was some sort of virus. After about a year it was almost gone. Interesting about the malts, guess I need to try harder lolI lost my sense of smell around the same time but gladly it hasn't stopped me enjoying my malts.
However it certainly has its disadvantages that you don't notice until it's gone. The ENT consultant couldn't give me a reason why it went or the likelihood it would ever come back sadly.
