I quit in '94 after 25 years of smoking.  I started when I was 15.  I knew I had it licked when the smoke stopped smelling good to me!  Now, I can't stand it!
Congrats, Allison and, yes, I also felt that just one would start the addiction over again.  Now I smoke an occasional cigar but never a ciggie.
Good for you!
