I didn't quit smoking cigarettes. Discovered that I had forgotten to smoke at some point and haven't had the desire to smoke again since. I basically vaped when I could and smoked when I had to.
There were not as many options when I did it. I got what is now generally referred to as a standard Joye 510 starter kit. I enjoyed my American Spirit non-filters, but was looking for a way to have more, ummm... quality (yeah let's use that word in a PG forum) quality time with girlfriend. The battery charge life, quite frankly, sucked. If I was lucky a battery would go for half and hour before it needed charging and it took at least 1.5 hours to recharge. I ended up getting many batteries, chargers, and a PCC. I still vaped when I could and smoked when I had to. Believe it or not, it was not the issues with batteries that stopped me from switching over to vaping quicker, it was the juice.
In the beginning none of the juices I tried tasted good and even the ones that were OK never satisfied me like a cigarette could. I kept trying different nicotine levels. I noticed when I vaped over 36mg that my desire to smoke was a bit reduced, but I wasn't satisfied. I kept trying different flavors, but I vaped when I could and smoked when I had to. One day I ordered the stupidest sounding flavor I had ever encountered. It was mostly a joke, to myself, because none of the flavors (tobacco flavors) tasted anything close to good to me. When that juice came I announced the joke to the household and dripped it into a BF modded cart. (kids, ask your parents about BF and modding carts as those were the old days) I popped that cart on and vaped and that stupid/horrible sounding juice actually tasted good. Second vape gave me something I thought vaping would never give me, satisfaction. I felt as if I had just smoked a cigarette, but it tasted like German chocolate cake, and for reasons that boggled my mind, that was great when I thought it would be horrible.
Since that first satisfying flavor, there were others that I found, but I still vaped when I could and smoked when I had to. One morning, while getting ready for work, I noticed there was one cig missing from the pack I put in my pocket. That was the same number missing as the morning before. I realized I had forgotten to smoke. I carried that pack, with one missing cigarette, around for months afterward, for just-in-case. I never smoked another cig from that pack or any other pack. One day I gave them, and a lighter, to a homeless guy who wanted to bum a light.
I'm pretty well convinced that the flavor that "works" for a vaper is never what they first thought it would be. In fact I'm betting it is probably a flavor that they never would think would "work". I'm also convinced that if you want no stress, then vaping when you can and smoking when you have to while looking for those perfect flavors, is a great way to leave burning tobacco to go its own way while you go yours.
