I just want to wish you success in quitting. It is an extremely difficult habit to break but if you are determined and get past that first week, you can be home free. Remember that smoking is a two part addiction, the nicotine physical addiction and the actual physical habit of just lighting up and associating a cigarette with various activities. When I quit 10 years ago, I took up knitting socks to keep my hands busy especially in the evenings. I had to focus on what I was doing, learning the process, etc and while it helped to keep my hands busy, I had to stop at some point and that is when I wanted a cigarette. All I am saying is be prepared. I used to call my sister and tell her I was taking a "cigarette break" just to break the pattern and habit, this worked for me as I was totally determined to quit.
I am so glad that I finally quit and there is NOTHING in the world that would make me take one more puff. Wishing you much success.
Now if I could develop such determination in breaking my sugar addiction!!! I am working on it though.
