I also tried the e-cigarette. Can't say I am a fan. I ended up spending a lot more money, and then my e-cig broke and I had to replace it. More money. And no matter how thick you make the vapor, it just isn't smoke! Not the same.
Yeah it will take some people longer than others to get used to it. My friends at work that use e-Cigarettes swear by them now - and enjoy the fact that you can change the flavours, cheaply too.
As a non-smoker I can't really appreciate the difference between that smoking feeling and the e-Cig experience.
