I quit smoking last winter right before an ambulance ride to the hospital and heart surgery. (Heart surgery is no fun, thanks for asking.) I smoked and quit and smoked again and quit again many times. The last time I quit (before this time), it lasted over nine years. Then I picked it up again during a very stressful time at work.
Frankly, I miss smoking. I don't miss the health effects, but I miss everything else about it. I can't say I won't smoke again. I've said that too many times to believe it.
And I miss smokers, mostly. They are a friendly bunch.
I remember times scrambling around airports looking for a place to smoke. Most are outside, and many are situated such that you end up having to go back through TSA screening again just to have a butt before getting on a flight. I wish I'd known about this site back then.
