I suffered from covid in September, no Hard Symptoms, just fluey.
3 weeks out of quarantine I suffered total loss of smell, and 3 months later I would say I have 10% of it back. 
Over the last few days I've noticed an intermittent sense that I'm sitting in a cigarette cloud. Brings back chilling in The Local Arms with Mirage and Lemonade grooving along to Fine Young Cannibals. 
It's not quite a taste, not quite a smell, more of an overall sensation of acridness.
We've got a Woodburner, I'd attributed it to perhaps a rope failure in that until I experienced it in the essential Spirit aisle in Waitrose. 
And today I was in the middle of a field many miles from home, so I'm ruling out Woodburner or smokers outside a supermarket.
AIBU to ask for any other's similar experiences?
