Take a 2 week vacation. Quitting smoking is more about breaking the mental habits that associate specific behaviors with lighting up. They physical withdraw is bad, but short lived (3-5 days). Everything else is mental, which is less severe, but lasts a long time. I've been off the smokes for more than 5 years and still have cravings occationally.
Get over the physical withdraw, then take a vacationand go someplace interesting to break your daily habit pattern. It will help you waeken the neural connections that associate cigartettes with specific daily activities.
