I was completely off smoking for about 6 months, then fell back into smoking for a month, followed by solely vaping for the last 4 months. I still frequently "desire" a smoke, but thanks to vaping I don't "need" a smoke to keep my sanity. When I think I want a smoke, I just remember all the downsides of smoking that prompted me to take up vaping in the first place. Those thoughts coupled with the sheer inconvenience of smoking are typically off putting enough to make me forget all about it for a while.
