Patrick- I'm in the same boat as you. I know I need to quit but feel kind of hopeless that I will be able to do it. The replies in this thread have been awesome. I really like the running idea. Here's some sites that I think may help.
1)
http://quitnet.com/ This is a big stop-smoking online community.
2)
http://cognitivequitting.com/ Very interesting site that addresses the habit and how to break it.
3)
http://quitsmokingonline.com/ A free online stop-smoking course.
