Understand that you will always have cravings. Strong at first and they will fade in time. But, you will always know what a cig feels and tastes like and that's OK.
You will see somebody light up and you'll think, "Ha! That looks like a good idea. I'll have one, too." which is how smokers trigger other smokers to smoke. Just understand that that feeling *will* come. When you feel it, that doesn't mean that you are "still a smoker" or "quitting didn't work." No, it worked. Being able to relate to smokers will always be there. Be aware of it and control it.
