Glad Dave's back. Hang in there Dave. You are in good company. Many of us have quit smoking for health reasons. Even George Harrison (bad example, but he was such a wonderful person, wasn't he.) quit and quit again. It's a habit, just a habit, only; it's not who you are, it's not really part of you. It helps to remember that -- I think. Then, when the habit drops away, or goes away, you're not surprised and you haven't lost anything. You're just a little more free to be yourself, despite the limitations of the human body; congratulations on your great progress.
