Why?

Why are you quitting?  This may be the most important step in actually not lighting up again.  Explore your reasons -- share with us.  They don't have to be altruistic -- whatever works(ed) for you is really all that matters.

I quit because it became too expensive to smoke.  When I started smoking I could get packs for 30-50 cents in the States, 25-50cents in Australia (I remember searching for pennies to be able to buy a pack -- while still in school).  I quit when they went up to $2.75 US -- apparently that was my breaking point.

The point is -- you have to find a reason to quit, otherwise it usually won't work

I'm quitting because smoking is seriously unhealthy.  My morning breathing is getting slightly more difficult; My husband hates it and will not talk to me while I smoke; I irritate friends by bumming smokes all the time; It costs to darn much; I want to be heathly when I get pregnant; the cigarette ban in bars will make me homicidal if I don't quit now;

Reason's I haven't quit yet:  I like it.  I'm addicted. I'm lazy.  I hang out too much with other smokers. I have too many drinks that seem to require a cigarette.
