When I first started vaping, I didn't necessarily expect to quit smoking. I had only tried to quit once before, and it had only lasted a few hours. I didn't try all the different methods. That one try was enough to give me the information I needed to already know that they wouldn't work anyway.
So, I didn't have high hopes for e-cigs either.
I just figured I'ld give it a try and see if it would, at least, help me cut back whenever it was important (like before a job interview) and maybe even keep me from having to go outside to smoke while I was at home. For me, it was only about the smell that kept me from smoking inside and that let people know that I was a smoker.
I got my kit and practiced on it for a couple of days. On the third day, I only had one cigarette right before bed that night. It's been one and a half years since that day. I've never had an urge for a cigarette in that time. But, I have missed the ease and simplicity of smoking. Just light the end and done. I used to miss that, but just now realized that I don't even miss that any more!
Anyway, to the reason for my post - finally.
I just wanted to say that I very likely wouldn't have quit if I had been out of cigarettes and didn't have anything to fall back on, if I felt like I HAD to do it cold-turkey. I had several packs of cigarettes laying around when I started vaping. After a few months, I gave them away.
