There's one side effect of smoking that I can't ignore anymore. The look on my 7 year old's face every time I light up. The tears in his eyes when he asks when his mom and I are going to quit. I would go through any one of those symptoms that you listed if it meant that I can make my son happy that his mom and I have quit smoking. That's my motivation. And because of that, I know I can do it. I know WE can do it!
