No lie, I've forgotten my vape before leaving for work a handful of times. Surprisingly did not ruin my day. Hell, quite often I forget to vape on my breaks and it doesn't stress me out any.
Vaping 0mg was easy enough for me to accomplish. I had been a 3mg vaper for a long time before one day, I decided to leave the house with 0mg. Didn't miss the nic even a little. Now, I occasionally vape 3mg for recreational purposes. I keep my tolerance low enough by vaping 0mg that when I vape 3mg, it actually does something really pleasant for me.
That being said, I still do vape... ...quite a lot by vaping standards in fact. But I think that if I didn't enjoy it so much as a hobby or even just saw a real unavoidable reason to quit (such as not being able to afford it,) I would be able to put it down indefinitely.
How that would really shake down in the long run is anybody's guess. Our addiction is a deeply psychological one. Most people who quit smoking succeed for the first month. Many even make it past 3, which is well beyond the threshold for physical habituation and arguably even surface-level mental conditioning.
Unfortunately, regardless of how they quit, by the 6 month mark, roughly half of them have relapsed. People don't give the hand-mouth thing enough credit. I think to pull it off, you have to really examine your habits and their causes. Look at how you cope with and react to stress very carefully. It probably helps to have a lot of control over the biggest stressors in your life... ...or at least be more apt at managing them than you were as a smoker/vaper. That's going to be the most critical and perhaps most difficult step. You have to fundamentally change the way you change the way you feel. That wasn't a typo. I'm serious.
I sometimes wonder if maybe the reason that vaping works so well as a means for quitting smoking has to do with the fact that you are replacing something that fulfills a need rather than eliminating the need completely, the latter of which is something you will likely need to look at doing in order to succeed.
