First off, it is good to be like Johnny.
Anyway, I remember what you are talking about when dealing with non-smokers and never-smokers early on in my quit. Many are very supportive and happy for you...for a few days or weeks. After a while, they just assume that you are over it and that quitting smoking wasn't that big of a deal. It doesn't work that way, normally. As ex-smokers, we have centered our lives around cigarettes for a long time and the healing process with quitting does take time. It gets much better but there are many ups and downs early on as you try to adjust to living as a non-smoker again.
That's what never-smokers don't understand and that's why I found seeking the support of other quitters on the message boards to be extremely useful in the quitting process.
Keep up the great work, My life. You are doing great.
