You CAN do it.
Will you do it? That will be up to you. I first encountered vaping about 6 years ago and quit for a short time, but returned to smoking. Then I dual used for a while, until returning to smoking alone for a couple years. I eventually got so sick, I decided to try vaping *again* and I was fairly sure I wouldn't be successful, in fact almost certain I wasn't going to be.
Well, every quit is different. This time around I dual used for a couple of weeks, and slowly and steadily decreased my intake. I used WTA e-liquid (Whole tobacco alkaloid, it contains some of the other stuff in cigs that causes brain satiation besides nic) while I detoxed of tar (which is also psychoactive, actually). I took a leave of absence from work, and since I'd had pneumonia for 18 months straight I think they were as relieved as I. It wasn't easy, and I've fallen off the wagon from time to time (found out I am a stress smoker) I have been cigarette free enough for my doc, my own body, and whatever else to note vast improvements. It took experimenting with gear, which does change rapidly, e-liquids (I discovered I was PG sensitive, which is an ingredient in e-liquid which doesn't HAVE to be there in great quantities) and that I liked high resistance with low power and high nic. I have learned to DIY my e-liquid, and enjoy that, and build my own coils, and most of all I have been for 99.9% of the time, cigarette free. I have occasionally stressed out and smoked one, but I didn't let it lead me back to vaping, and that's the great part for me.
Now my husband who smoked since age 8 is starting the process-- dual using, with WTA and etc. He's doing okay. I was a 3 ppd smoker by the end, and to be honest it took the threat of COPD and what THAT lifestyle was like to achieve it. But vaping CAN be accomplished, it's a bit different for everyone, it's normal to be afraid of quitting. I just followed one piece of advice here: keep vaping.
I experimented with a lot, but I vaped before (and after) every cigarette to reinforce being a vaper. I made it through detox, and am now (apart from times of insane stress) a non-smoker, and I am working on extinguishing that Very Occasional (probably ever 3 mo, sometimes I didn't even finish it) Stress Smoke, but identify as a vaper, and imagine I will continue to do so....
So yes, you can, just keep at it, come here for questions advice, support, etc. Vaping may surprise you, it did me, and I had tried vaping before.
Best of luck,
Anna
