Motivation to quit?

I just finished my pack and am hoping to be able to quit this time around. I've manage to lose 40 lbs over the last 1 1/2 year by joining SparkPeople, they have a great site. Not just about diating but really about changing your lifestyle. I've improved my eating habbits and  exercise 30 to 60 min. at least 5 days a week. I've  been looking around for a good strength machine and love the Bowflex but thought it was to expensive. But been doing a lot of thinking lately and figure a pack of cigarettes cost me almost $10.00,  so for every day I don't buy a pack I can put that money for my Bowflex and won't see the difference in my spending. The pack I got when I decided to try this out lasted me 5 days. Now I want to see if I can finely kick the habit.
