From my experience, there was no magic bullet. It's a decision you have to make. For me, it was not as easy as others on the forum have said it was for them. I did quit analogs on day 1, and have not had one in over 3 months, but I still think about them daily. For me, vaping has been a nice substitute but not an all out panacea. In my search for that perfect "replacement" I went out and bought waaaay too much equipment, including a ProVari. I won't lie. Vaping does not give me the same satisfaction as smoking did and may never. But, every day gets a little better and a little easier. Part of it is having the right equipment (still searching for a great cig-a-like - which doesn't yet exist), part of it is telling yourself that you stopped killing yourself slowly, but the biggest thing that helped me was to just stop buying cigarettes. If I don't have them, I can't smoke them. And that my friend takes discipline, which is a fairly new concept to me, even at age 51. I've actually surprised myself.
While I know it sounds cliche, but when it comes to vaping vs. smoking, if I can do it, truly anyone can.
