It's been 21 days without a cig for me, and here's what did the trick to get me off the morning and before bed cigs. (Didn't really think I ever would quit completely.) I took my regular cig and a comparable flavor, (menthol for me, 24 mg), outside in the garage, and smoked both side by side. I did it twice, once with wine in the evening, once the next day with my coffee. For the life of me, I could not tell the difference, until the end, when the cig started tasting something like an ashtray, and the e-cig tasted clean and somewhat sweet. Obviously better.
I smoked for 30 years, and that did it for me. There was no difference, other than the e-cig flavor won out in the end, and I just couldn't believe it until I absolutely, literally, proved it to myself. Now, that's what I think about when I get a rare craving, and I will vape the same flavor if I have to. Funny thing is, I don't have to, and this is way more fun, as there are so many great flavors to vape, and we only used to inhale one "favorite" before. Go figure. Give it a try; you may amaze yourself. I accidentally quit, without even trying. I was okay with one or two a day, but I don't even think about it now. Huh.
