This. I know 'nicotine' is already here, but it's not the same.
Confused the hell out of me when I was trying to switch to vaping that I'd keep going back to cigarettes - "I'M GETTING THE NICOTINE, WHAT THE HELL?!", and it wasn't just habit, it was overwhelming need to smoke.
I finally figured some of those other 2999 or whatever chemicals in there must be addictive too, or something, I don't know.
I've quit drinking, when I was a daily drinker at risk of a seizure because my body had grown so chemically dependent on it. I've quit countless other 'behavioral' addictions.
NOTHING, was as hard as trying to quit smoking. Until, thank the powers that be, I met vaping, and after a couple months of back and forth, was able to transition to it entirely. Haven't had a cigarette since, and it's been at least 10-11 years.
Eventually lowered my nicotine to 0 mg, then gave up the vaping. Haven't done either since. That was, probably 8-9 years ago now.
I still get the odd craving to vape. Zero cravings to smoke up until last year, first trip in my life to Vegas (and two more since). The casino environment with everyone smoking, I don't know what it is. Got me looking at it with the rose coloured glasses occasionally while there - but then I quickly remember how hard it was to shake, and how happy I am without it.
Lengthy convo about it in response to another comment, that may have some helpful tips!
