Good job dude. Clicked on page 4 after reading first page hoping to see you had stuck at it, and its great to see you have!!
I quit smoking, kind of, a year or so ago. I vape now. I smoke a tiny bit of tobacco with weed most days still though. But I dont smoke cigarettes anymore. Its weird.. I just.. didn't want to smoke anymore one day and found it quite easy to do despite trying to quit several times in my life. The taste of a strait cigarette now to me is really gross. I'll do it out of absolute desperation if I've lost my vape and I'm somewhere remote. But I can only bring myself to smoke like a third of it before I'm grossed out and regret it.
I didn't find quitting oxy that hard, or alcohol when I got mildly addicted to both of those. I just stopped when I felt like it was getting out of hand and felt bad for a week. Cigarettes I feel never give you that 'oh shit this is getting out of hand', or at least not until its late in life and you have seen a bunch of family die like you have. Its not as instantly 'bad' as other drugs so you can just drag the addiction out for a long time without it really getting to you.
Do you plan on quitting nicotine entirely? Personally I can't see myself ever giving it up. I feel at this point in my life I have so much owed to nicotine in terms of productivity that if I stopped my world would fall apart lol. I am convinced it is the best brain/cognitive enhancing drug on planet earth. That might just be the nicotine talking though.
