My theory is to get the nicotene out of your body ASAP. Sure nicotene gum, patches, ecigs might save the lungs a bit (notwithstanding what they do to other parts of the body) but in order to stop the addition you have to stop administering the addictive substance. If a cocaine addict was trying to quit cocaine, you don't do it by giving him cocaine. My way was cold turkey with rewards (at first every day, then every week, then every month). Rewards are so personal and I can't recommend anything other than to suggest to reward with what you would like be doing if it was your last day on the planet...something that will blow your mind with pleasure. Set aside some "reward money" and believe this is one of the few things where the end justifies the means.
I don't expect this theory to work for everyone so good luck with your method and hope it works for you and others who try it.
