When you start vaping, do not look at it as a way to quit smoking, or as a device to replace cigarettes. Simply treat it as something new and enjoyable in your life. If you feel the need to smoke, then do it. The best advice I have seen is if you feel like you need to smoke, make a conscious effort to vape first. Only smoke after you vape. The most noticable things I see on this forum are the number of folks who say that they "just stopped" smoking at some point after they started vaping.
Treating vaping as a stop smoking aide, puts pressure on you to make make vaping work. Treat it as something that stands on it's own merits. It tastes good, it's clean, and it delivers nicotine. Vape because you enjoy it. Most of us have found that after vaping for a while, we just started to dislike analogs. The smell, the ashes everywhere, the burnt clothes, burnt furniture, running out of them at inconvenient times, the list of negatives to smoking goes on and on. After vaping for a bit, the analogs will just seem to lose their charm. The last analog I smoked was very unsatisfying. Nicotine without the exquisite taste of a nice liquid behind it becomes very unfufilling.
So... For now, you are a smoker and a vaper. Give it some time, and enjoy both with no pressure on yourself. If you want a cigarette, do it, but vape first. My bet is that pretty soon, you too will no longer enjoy smoking. When that happens, you do not "quit" smoking, you just stop doing it.
