Northerner I know exactly what you mean, I'd probably enjoy one too, despite my loathing of smoke/the smell/the cost etc but it would never be 'one' for me so it must be 'non'
I see myself as an ex-smoker and never think I'm a non-smoker whereas dh (who quit when I first did 14 years ago) always sees himself as a non-smoker despite the 20 years of Marlboro previously. Once he'd stopped and beaten the nicotine goblins he accepted that was it, finished. Needless to say he sees life as black & white with very little grey...
You survived the day, tomorrow may be as bad, it won't be worse and you'll get there. Right I'll shut up , not before time !
