I found that on my umpteenth attempt to BECOMING A NON SMOKER I just fed the addiction with whatever it took. I started with inhalators, then gum, then weaker gum and then nicotine lozenges. In the end I just realised one day that I would get as much satisfaction from sucking a mint.
That was it, no more addiction. By that time I had been a non smoker for long enough to have no desire to smoke left in my addicted brain.
Cravings are just a trick your addictive brain is playing to get its addiction fed. Eventually it has to lose in order to finally break the habit.
You have done the hardest part Ed, just the final push to go. Don't hurry it, take your time. You can, theoretically stay on NRT for the rest of your life if you need to. Nicotine is not the damaging ingredient in tobacco (in moderation - before you all remind me that it is deadly poisonous in large quantities) it is the rest of the crap in smoke that kills.
Let us all know how you get on........
