it is amazing how after we have been quit, we truly know there is no reason to smoke and don't want to. Smoking would just make you a miserable addict again. I am so proud of you and my heart goes out to you. I know you have the strength to get through this and I pray that your son one day chooses to see how worthwhile his life is and make changes to see the truth.
One thing I know.............your quitting your addiction taught him strength.
