after the nicotine is gone, quitting smoking is more about breaking the pattern and the thought process that smoking has so engrained into our behavior.
my third day I learned to laugh when I got a crave. it became the smoking replacement. the change from the smoking norm. every time I thought of smoking I laughed.
After a week I was thinking about laughing instead of smoking.

The rubber band on the wrist breaks the normal thought process.
Simple reminders that aren't difficult or painful.
Eventually you recognize why you're doing the new behavior and can let it go.
It's a process. Keep them away from your face long enough and you forget about smoking.
