As someone who quits benzo, alcohol addiction and multiple times paused nicotine (snus and tobacco-less nicotine pouches, which has much higher nicotine content) its actually walk in the park, outside of the fact that you get really hungry, which is shit side effect, but it is what it is.
I find much harder to quit caffeine, especially as someone who has low blood pressure, without it, I just feel lifeless for half of the day, makes me depressed, etc.
I think if you have something like Nicorette products in your country, those are pretty good tools to achieve complete glob...cough...complete nicotine avoidance.
But realistically, if you just lower your nicotine intake and use tobacco-less product, there is little to no harm. I am talking mini pouches of zin, 2mg max, few per day. And this is coming from extensive discussion with doctors since I am after transplantation. You diet is most likely culprit for heart problems, big cholesterol levels, etc. Even tho, vapes are shit and I would never inhale that shit.
Just that it sucks that when it comes to smoking or vaping, you have patterns in your brain, that you will miss the movement with your hands, inhaling some vapor and that you have something in your hand, etc. Being addicted on nicotine pouches means that feeling of having something under my lip can be resolved by mint candy there instead, not such luck with smoking.
But realistically, nicotine w/ds are highly manageable, for added anxiety there are miriad of medications (just refuse Benzos if offered, that is single hardest quitting substance, which you came across, coming from actual hard drug addicts and I confess that its the single hardest thing I've done), etc.
