In the beginning of your quit, and, for quite awhile,
It feels unnatural to not smoke.
We can get fidgety after we quit.
Which can lead to discombobulation.
I cut a straw into thirds and I would chew on them.

Some use flavored toothpicks.
A rubber band on the wrist.
Find your distraction.
It's easier to let go of later than letting go of smoking seems now.
