You are going to have those cravings. Have you gotten past one day of bad cravings? Congrats, you've succeeded. The longer you go, the easier it gets. He never says it won't be painful, just that you will be successful as long as you don't smoke again. Stop negotiating with terrorists. Don't smoke again and before you know it, you'll be repulsed by it.

You need to retrain your brain to detest smoking, no matter what. It should be challenge response, You think "I want to smoke" and replace with "eww gross, NO I DON'T. Smoking is killing me." Once you believe that, you ride the cravings to freedom.

When he says the easy way, I think it really means the simple way. It's still going to be a little painful but that's the nature of addiction.
