I've developed this strange aroma/breath smell that I struggle to describe. It's a mixture of a sweet/sour, chemical smell that sometimes veers on a bit smoky. I can smell it with my mouth closed, meaning it took a while to realise it was coming from my throat. I thought it was something odd in my house because it wasn't consistently there ad seemed worse in the evening.
It first appeared late last year and persisted for a few weeks, then went away. Since the start of this week, it's back and driving me mad.
Has anybody else experienced similar?
