I quit over a year and a half ago! (I quit February 13, 2010) I had smoked for nearly 8 years since I was 18. There were some month long periods where I was forced to quit because I kept getting bronchitis and almost pneumonia. So, I mostly quit for health reasons. Also, it just got too damn expensive, and I just hated how dependent I was on them.

I stopped cold turkey. I just stopped buying packs. It was hard at first, especially while driving and at work. But, I grew to forget the need for them. 

I managed to do it, and I know you can too! Don't give up!
