Hey Aaron, way to go.
I have quit numerous times, but like to smoke so pick it back up after a year or more of not doing it. I do this to mitigate the bad of smoking. A year of letting my lungs clear out a bit then I go back to it. I accept smoking is bad so do my best to reduce the risks while still enjoying it.
That isn't a suggestion you do the same, just a little history of me and how I have
experience with quitting. I have developed a method that works for me, for others mileage might vary.
1st step is reduce the amount by only smoking every other time I crave. This seems to work fairly well, and as I do it the time between cravings gets longer and longer.
2nd step is hanging out with more non smokers. Smoking becomes a social thing and being with others who smoke makes me want to do the same.
3rd Once I have reduced to very few. Like you did. I quit cold turkey. I remove all vestiges of smoking from my life. Lighters ashtrays etc. I know I will not smoke.
4th I have never used any nicotine patch, vape, etc... When I say cold turkey I mean it. No judgement on others who do though.
5th Embrace the suck. The first 2 weeks or so suck. Everything seems to trigger a craving. I get moody, friends who still smoke become enablers just to get the nice me back. But I will explain to those friends and family I might be moody but it will pass.
6th Recognize I might relapse, but I don't let that drag me back into full blown smoking. If I "cheat" I don't let that stop me. But try and figure out what made me do it and try and find ways for that not to happen again. Like was it because I visited a bar and I associate drinking with smoking. Then maybe until I know I can control it, don't drink. Or it might be a coffee, or the many other things that can trigger the craving. Maybe it was stress. That is a hard one to avoid, so if it is something out of the ability to avoid, I look for other ways to manage. With stress, there are lots of helpful methods. From squeeze toys to screaming into pillows etc..
7th Big thing here too is not to substitute one bad vice for another. For example, don't become an over eater. Or that annoying sunflower seed person who is spitting seed shells everywhere. I know a lot of people try and substitute oral fixations. But I try to be careful to not create another bad habit. If I do anything it is toothpicks and even then I try to limit how much I use that to substitute. I am not trying to switch habits, I am quitting one bad habit.
8th enjoy being a nonsmoker, but don't forget to be empathetic to those who haven't been able to quit yet. You were once them so remember not everyone reaches the same point at the same time.
Hope this might help you, or someone else. Keep it up Aaron, just know no matter how hard it gets you can stop. Put your mind to it and you will do it. You might have set backs or temptations, but you will get there.
