My last cigarette after I started vaping was a horrible experience that I'll never forget. Haven't touched them again and have no cravings whatsoever after 10 months. If you have such a strong craving, light one up, it may very well be the last one you'll ever light. Remember it's the cigarettes you avoid smoking not the ones you do. The more you deny yourself something, the more your brain obsesses about it. This is not a painful process, it's actually a very smooth transitional process. Remove the label you put on yourself as a smoker and always a smoker to a vaper for life. It's really not the same thing anyway.
