My path was exactly like yours. And I agree with your second paragraph. We're all different. There isnt only one right way to quit smoking. The right way is the one that keeps you from smoking.I smoked even with a patch on.I was the opposite. It was a cigalike that got me off. Then again, it was a Vuse cigalike, which is 48 mg nic. It was only after several months that I started to hunt down other solutions to move on to as U saw the pile of empty expensive cartridges (which weren't even all that empty, just cut of by the built in chip) stack up that I found "real" vaping.
I do believe vaping offers smokers an effective path off cigs. But just as some people are successful with patches, gum, or pills, it's all a matter of discovering what works for the individual. Let's face it, not everyone who takes up vaping stops smoking forever. A lot do, a lot don't. It is one more tool to stopping, and one of the more effective ones, but it's not 100% effective, and I would encourage anyone who fails at vaping to keep exploring other solutions, even returning to try vaping again down the road when either they are more open to it, or whatever personal dislike has been corrected in the market.
I quit cold turkey for months. I smoked with a patch on. None of these "took". The first time I had a stressful incident it was right back to smoking.
With vaping it's different. A little over two years vaping, plenty of stressful incidents and didnt even think about smoking.
And I agree that @Mitesh Patel needs to up the nic. There is plenty of time down the road to decrease it. I would start with 18 or 24.
