Two years ago, I decided to properly quit, went cold turkey and did quite well, right up until christmas last year. I felt miserable, so went out and got a pack, after all, what is one packet right? Well, a couple of months later, I was still smoking, and came down with a particularly nasty cold (stupid winter that never ends), you know the kind of cough that once you start, just doesn't want to stop until you've ejected most of a lung. Well, after a few days of coughing my lungs up, I decided that I was desperately needing a smoke to calm my nerves.. and it was the worst taste I have EVER experienced, but I figured that I was just not breathing smoothly, as I was quite short of breath at the time. Another few days passed, and I tried another smoke, and the result was the same, one or two draws upon the cigarette, and I stubbed it out in disgust.
On that day, I threw away almost an entire pouch of tobacco, all my papers and lighters (except one in my toolbox). And the ashtray got relegated to the pit under the sink.
I've not touched a smoke since then and hope this will remain so for a long time to come. Yes I was addicted to smoking, and I enjoyed it, and I don't care what people think of me for that, I don't drink alcohol, and I don't judge those that do.
As for people that criticise those that use the vapour things, I would point out, that by making the switch, they are removing almost all of the toxic byproducts found in cigarette smoke, which in the long run, is better for them. Or is it the 'second hand vapor' that you have a problem with? hmm.. better not use the kettle in future.
