I'm also a #3. I smoked for 30+ years, well over a pack a day. While researching for my first purchases I felt fairly confident that I'd at least like it enough for it to displace a portion of my cig habit, especially since I'm another for whom ability to satisfy hand-to-mouth and sensation of inhalation aspects is probably most key. (And yes, was also enthusiastic that it could improve the chances of being able to do that despite given locales.) But I never would have believed that shortly thereafter I'd be completely off cigs -- and by 'accident.' Zero intention of that going in.
Six weeks before that I'd been visiting family, and reiterating flatly that there was no foreseeable chance that I'd ever try to quit. Would have needed a major motivation if not personality transplant for that lol. Said the only way I could think of at that time that I'd even consider would be something like a two-week specialized spa or retreat (read: non-hospital) program to kick things off, which if they exist (I looked once and was surprised by what I didn't find), would cost what, maybe $25K? Don't think so! If you'd told me then that not much more than six weeks later I'd be off cigs, I'd have only been able to guess that I must have gotten the baddest of bad health news or something... But even that wouldn't have necessarily made sense, since I'm probably the type who, if given the WORST of bad health news, would see it as making quitting rather irrelevant at that point.
Then one day I finally followed through on the mental note I'd made a few years ago to occasionally check up on whether this Chinese "Ruyan" thingamajig I'd seen mentioned in some obscure place ever made it to the US in a reliable way... WOW. I was simultaneously thrilled yet dismayed at all I'd somehow managed to miss out on during that time!
Also shortly after beginning to vape, there was the first very serious health emergency with my 80-ish mother in another state. I never would have believed that throughout the stress of arranging to and then getting out of town ASAP; then throughout a five+ hour drive to her state; and throughout a week of practically living in her room in cardiac ICU, on a sprawling tobacco-free campus in deep snow... I'd feel virtually no need for a real cigarette. Then came weeks of single-handedly trying to provide some holiday spirit, decor, festive meals, etc. for my small family, and doing all chores for my parents... And deep worsening of anxieties over where all that goes from here etc. etc... STILL no need for a cig. And I'd already been in my own personal rut before all that and before the ecig. (But not the kind that finally spurs you to some kind of action!)
Just amazing. I was THE LAST person who could have ever been expected to quit smoking... and just by 'accident.' In the middle of about the most stressful time in my life. And when I was feeling no motivation/willingness to put myself through anything at all to improve my lot.
