I didn't think I'd ever give up smoking. It took me 14 months of vaping and many, many attempts. It was far from easy for me, I had to make up my mind to go through the discomfort and then see where I'm at. I think that the secret for me, other than making sure I was getting enough nic, was to take it one hour at a time. Then once I had some real hours invested, I would take that into account whenever I got a strong urge to smoke and think, well I want to keep this experiment going instead, which is what it was.
So I stuck with the experiment long enough to finally get myself in a position of power, which meant I was in control now of whether I smoked or not, for the first time since 1978 when I started smoking. For all these years I have been a slave to smoking, I do think that this is a good mindset to take, not looking to quit necessarily, but to just get control over your life and then you can be in a better position to decide whether you are going to smoke or not.
So that's what I did, now I can choose to smoke or not and the way it turned out is that I now choose not to. Being able to choose, in itself, is way cool.
I can't emphasize enough though that if you are struggling a lot, you need to make sure you are getting enough nicotine. There are a bunch of other things that you get addicted to and have to break the addiction with from smoking, the other stuff you can't control other than with enough resolve, but with the nicotine we can control it, although you may need more of it during the quitting process, and maybe even beyond that. 24 didn't work for me. 28 didn't work for me. 30 didn't work for me. 36 does. Your needs may vary, some people quit on 18, if you are vaping 18 or 24 and croaking trying to quit, moving up may be the solution for you as it was for me.
