For DMark:
The other two posts I brought up were on how you can't quit for another person. This one example is the exception to that rule. David will benefit from your quit, but you are the primary benefactor--never lose sight of this. To reap the benefits of a smoke free life simply entails always remembering why you don't want to be a smoker again and to always remember that to stay free now means knowing to never take another puff!
