I gave up about 9 years ago now
I was on holiday and about to buy 1000 cigarettes to bring back to the UK, changed my mind and bought a nicorette plastic cigarette, used that for a few months and haven’t touched one since.
It gets easier, there is virtually no chance any event would ever cause me to smoke again, however, I still do get occasional cravings. These usually last a few seconds a couple of times a year.
I think the key thing for me and what I see others fail on is that you can’t just cut down, it’s all or nothing
