This morning when I got to work there was a message on my voicemail that I would like to share.  I have not put in the caller's name to protect her privacy.  But this is the message she left:  "Hi Dr. Johnson, You don't have to call me back.  I just ran across your name and address when cleaning out some papers.  My name is Pat _____. I saw you three ago and three years ago on March 10 I stopped smoking. I had been smoking for 40 years.  I want to thank you because it worked.  I quit and never looked back.  Never had a desire.  It has been an absolutely marvelous three years. The most interesting thing is I can barely remember being a smoker.  So thank you, thank you, thjank you so much.  I've referred other people to you and I will continue to do that as I run across people who want to quit.  Again, thanks very much."  I ask people to call me on the first anniversary of becoming nonsmokers. Sometimes I get the calls years later. It's wonderful to get these messages and know they have used such a powerful tool to set themselves free from cigarettes and smoking.
