The anxiety over losing the ritual is extremely real. Then a few months later you will be sitting there, content after a meal, not needing to sneak off for a smoke and it will hit you like a ton of bricks... "wow, what other huge but stupid cognitive biases do I have which are holding me back and making me miserable?"

Quitting cigarettes is about as close to a state of enlightenment as I've ever gotten. Being absolutely disgusted with something you were happy doing a few months ago is a really powerful ego transcendence event.
