I went to live with my Dad while he was bad, I did not smoke in the house, but he could smell it on me!!!!
While i was living thier, i managed to quit for 6 weeks, and he could still smell smoke on me.
During that period, one day i opened my wardrobe doors, and i smelt stale smoke myself, obviously my sense of smell had come back to me, so i washed everything in that wardrobe, 2 or 3 lots then i had to iron it!!!!!, and i'm a man!! but i tell you it was worth it, a breath of fresh air.
My Dad did not complane again!!!!
Like I said just a thought!!!!
