I'm a firm believer in that in order to completely quit tobacco, you have to really want to quit and work at it. There are some individual smokers who were able to quit smoking easily by making the switch to just e-cigarettes, but its my guess that they are in the minority. So, you must be determined to quit.
I loved smoking but hated what it was doing to my body and health. I didn't think that I'd ever be able to quit though.
I had tried to stop smoking using the typical "approved" methods: Nicotine patches & gum, prescription medications, and even hypnosis. None of them worked for me. By chance, I saw my first e-cigarette in a convenience store display: an NJoy disposable ciga-like. It wasn't great, but it did seem to work better than the traditional methods. I did some research on Google and found the Electronic Cigarette Forum (ECF). The vast majority of what I have learned over the years has been from this forum.
I purchased my first ciga-like kit from Smokless Image. It got me off of cigarettes within a week. I knew that I would have strong cravings for tobacco, so I allowed myself a few cigarettes a day. I vaped as much as I wanted, when I got a strong tobacco craving I vaped even more. When that didn't help, I allowed myself "half" of a cigarette and saved the second half for the next bad craving. Those second "half" butts tasted nasty, but I believe that helped me to quit. Before the week was out I was vaping only and had no desires for those nasty cigarettes.
Within a month I had upgraded from the ciga-likes to my first mod and never looked back. I haven't had a cigarette in five years and haven't wanted or touched one since I smoked my last one.
