I'm addicted to nicotine, though not cigarettes (though I do smoke on social ocasions, but the nicotine in just one cigarette available in the EU does nothing for me), and I've "quit" numerous times for months, but my (undiagnosed) ADHD brings me back to it.
It is such a perverse stimulant.
I've taken hardcore stimulants and never got addicted, but nicotine has such a small half-life that it's impossible to not get addicted.
While I'm on more powerful stimulants I don't need nicotine to do my work(in fact I can go without if I don't have to work).
I suspect if you're using enough nicotine that you can't feel the effect of a cigarette, you're probably using a lot more than I was getting from smoking. I'm not sure if my advice is equally useful for you, but I hope you manage to kick the addiction cycle at some point.
I gave up after 20 years of pretty much constant smoking. I will cave and have one with a friend who still smokes while drinking once in a while. Not perfect but better than smoking a pack a day.
For the first year after stopping regularly smoking, I still felt the urge when drinking, and sometimes would have a cigarette with drinks on the weekend. After two years, I mostly stopped even wanting that.
For many years after, cigarette smoke still smelled good to me, although I had no daily urge for one. But eventually even the positive association with the smell faded, and now I'm back to the original state of thinking cigarettes smell bad.
Nicotine's hooks run deep, but they're not permanent. Stay away long enough and you'll eventually make it back to wondering why anyone smokes in the first place.
I think it's important for people who are addicted to know that quitting is possible — you aren't permanently rewired. And it doesn't have to consume your life.
