I stumbled into a local B&M shop with bronchitis from being with other smokers for a holiday adventure. Got an ego and an evod tank; the next week, without antibiotics, I walked back in to thank the guy who sold them to me. My lungs were clear, my sinuses were clean, I was breathing through both nostrils regularly after years of perhaps one at a time. Being that sick made it easier to forget about the cigs and just vape for my nic cravings. My voice was clear, and I wasn't coughing, not even the half coughs that come from smoking irritation.
It helped a great deal to be sick when I was quitting; by the time I tried lighting up again my taste buds had recovered enough to utterly reject the concept. Had I not begun vaping, chances are very good that like every other winter of my smoking lifestyle, I would have been on antibiotics, then spent a very harsh winter of relapses; that was the pattern every year for as long as I smoked.
So I vote with very little effort; once opened to the solution, I followed it with relative ease. There are a few black letter days, desperately just wanting to actually smoke a cigarette, that ended each time in violent physical reaction to attempting to smoke.
Five days after I began to vape, my regular cigarette order of 4 cartons arrived. I have 3 cartons, 9 packs, and 7 cigarettes of that left, to remind me just what it truly cost every time I restocked. There is no desire to smoke any of those cigarettes now, at all.
