I did. It is possible.
And, like many people, I thought I would not handle ANY kind of stress whilst or "after" - but my life started circling the drain, and I never ever smoked again.
And I was, to my shame, long-term, hardcore (although I don't think I actually smoked properly.....) 🙃
It is wise to develop at least SOME kind of strategy for the process, and your future ways of doing things minus the cigarettes - but that can lead to endless procrastination, so be careful of that.
You WILL however, feel so much better, and quite quickly as well - in terms of tasting food, feeling cleaner, having more money, having more energy and being able to take a nice deep breath.
It is a shame that "vaping" has been invented, as that is just another vice/delaying tactic, if you ask me.
