You will almost certainly have cravings when you quit, and they’ll almost certainly be both pretty intense and fairly frequent in the beginning. But, as long as you approach them the right way, they’ll get both weaker and less frequent with every passing day.
The right approach is not to fight the craves. In fact, fighting them is the worst thing you can possibly do: There’s an old saying, “What you resist persists.” Fight your craves and they’ll fight back. And they’ll wear you down; after all, they’ve had years of practice at this, and your resistance actually makes it easier for them to win.
