Paranosmia

Does anyone else suffer with this? I lost my sense of smell (anosmia) 6 years ago and although it has come back a little bit (probably about 30%) I periodically get this phantom chemical smell 'stuck' in my nose which is awful and makes me feel tired and irritable - it's almost as though my brain is constantly trying to work out what it is. It usually passes after a couple of days but we've been having some decorating done and I've now had it over a fortnight - I'm assuming it's the paint. Even being outside doesn't get rid of it. I know there's no cure but it's so darned annoying - just wish it was the smell of roses or something pleasant instead - chocolate maybe!
