I quit smoking after 3 years about 2 months ago. After taking a class in Neuroscience I learned that nicotine is the most addictive substance-- more so than heroin. (Mainlining as much nicotine as one injects w/ heroin will stop your heart and kill you DEAD)

Here is how I stopped smoking:
1. I stopped buying packs and began to only smoke if I found someone who was willing to give me one.
I eventually became really proficient at bumming... but my daily cig count dropped immensely.
2. I cut down on drinking during the weekends (I would go through a pack a night).
3. I told all of my friends that smoke to never, under any circumstances, let me bum a cigarette… which sucked… but worked.
4. After a month, I was down to one cig a day.
5. (most importantly) I then paired smoking with something negative... such as I could only smoke a cig. while studying, cleaning out my car, pulling weeds (any awful chore that I hate doing). This is tough to do but works the best... because you are basically tricking yourself to respond negatively to the idea of smoking. After a month of that crap, I was good to go. I haven’t smoked since and def. don't plan on picking the habit back up.

Do research, visit a hospital, talk to family and friends who have been smoking... motivate yourself to change.

It all comes down to how hard are you willing to work for it.

Another idea is to connect a sense of pride to your ability to fight temptation. As in, whenever you falter in your attempt to quit, adopt a sense of embarrassment or incompetence…

Sounds like a Dr. Laura tactic—but if you REALLY want to quit, you have to try everything.
