For me, the habit (of 30 years or so) was the hardest to give up. I stayed on the Nicorette for a couple of months until I was confident I'd beaten the habit, then gave up altogether.
When I write "odd twinge", I mean once or twice a YEAR. I can still remember that feeling of the first of the day... But also the disappointment and disgist of the second, third.... tenth...
Have also had a couple of dream smokes (and felt super-guilty in the dream!)
