I switched to vaping at the tail end of last year. It was my 4th or 5th attempt - and what changed was that it finally clicked with me that I didn't enjoy smoking, what I enjoyed was the break from the nagging feeling of needing a cigarette (the addiction). I'm - like many others - working down the strength of the nicotine in my vapes, and it's going well. I do not miss smoking at all - I am bloody loving the freedom of not having to do it - sometimes I forget to vape now, too - and it's wonderful.
My husband still smokes, though in the past few days he's started vaping as well, with a view to stopping. Yes, it (and he) stinks, but me nagging him is not going to make him quit any sooner, so I'm not - just insisting he goes outside if he needs a cig, which I think is reasonable.
I am so happy not to be a smoker any more - smoked since I was 12 or 13 (am 60 now) and I would have said I enjoyed it, I suppose, but still hated the feeling of having to do it, of always working out when I could pop out for a cig, of getting twitchy in the cinema if the film went on too long etc. etc. It's expensive too!
I'm not saying the OP and others are wrong to think they enjoy it - they probably do enjoy that bit of relief and 'me' time - but there are other, less dangerous and anti-social ways of taking a break.
