Hi Tryagain,
I have been going through exactly the same thing with smell. Although I never smoked in my house my closet smelled so bad from nicotine. It's a walk in closet and I had to empty the whole thing and wash the walls down, clean carpet and wash everything in the closet. Febreeze is helping also. I can't believe that is how I must have smelt.
I went to the dentist last week and was leaning over talking to the receptionist and she said "you smell so good what are you wearing" and I realised that nobody had mentioned my perfume before probably because I stunk of nicotine, and I can't tell you how good that made me feel. I find rewards in not smoking everyday and that stops me from giving into those terrible urges that appear from nowhere.
Good luck!!!
Hang in there.
