When I got my starter kit on 11/27/12 around 5pm, I immediately started vaping like crazy. I had a sampler pack plus some carts that came with the kit. I was amazed at the taste and satisfaction of the ecig. I thought it would take a bit of a transition to stop the analogs.
However, my wife and I would always have an analog just before bedtime around 10:30pm. I lit up the analog and took 2 drags before putting it out. The taste and TH was absolutely horrid. I was amazed it only took five and half hours to stop the analogs. I will admit that I have had some wicked cravings for analogs and stumbled a few times, but I have only smoked 5 or 6 analogs since 11/27. Maybe one per week I guess and I consider that a great victory considering I was a 1.5 PAD smoker before. Now the smell of tobacco smoke makes me gag and cough a bit.
The other night I was walking out of Wallyworld and a group of folks were standing in the parking lot smoking as I passed by. I caught a whiff of the smoke and it made me give one of those short coughs like non-smokers give to smokers when they are annoyed by smokers, which was not intentional on my part, it was a genuine cough. However, one guy in the crowd took exception thinking it was the "non-smoker's annoyed cough" and remarked "hey, at least we are outside."
I walked over and explained it was not as he thought and told him I'm an ex-smoker and explained about how I now vape. I pulled out my PV and showed him and the crowd. The next thing I know I'm giving an informative lecture on the ecig. I always carry vendor cards with me now and three folks in the crowd showed interest and I gave them my cards. I also put my email addy on the back of the cards for folks to contact me if they have any other questions. Later that evening I had an email from one of the crowd members thanking me for the ecig information and telling me he'd placed an order for a starter kit.
To make a long story even longer...

... this is like the 5th time I've given the informative lecture to smokers and now I have $75 of credit on one of my vendor accounts. So apparently I've "converted" 5 people to ecigs and have had quite a few emails. A few of those folks are on this forum now as well.
As usual, I've rambled on again
but if you've read any of my posts, I can't give a short answer
