I had smoked many years, but quit almost 2yrs ago using Champix

Time flies, it seems just yesterday I had posted my quitting smoking thread on here, and now as of June 8 2011, I have quit for 2yrs..... this is my second longest quit, and what I believe to be the final quit.
I am NOT going back to the one thing I can control about my health....goodness, I have enough other health issues that I don't need to return to chronic bronchitis, wheezing, etc from smoking.
