I gave up the Mary Jane in my late twenties. It started giving me panic attacks.
If only butts did the same, I would give them up in a heartbeat....but NOOOOO, they make me feel better.
I am starting to hate them. Perhaps this may be a first step for me.
I read a really excellent article - written by a former smoker - about that aspect - that act habit of smoking fills a void, or rather leaves a void, when you stop. Totally aside from any physical addiction to the nicotine per se. I wish I knew where to find it; was explained really well, and how the author dealt with it.
I’m thinking maybe starting a new “habit” that uses hands - or hands and mouth - knitting, painting or other arts; playing music, etc. Also one that involves others doing the same thing and it’s non-smoking group. Painting group, craft group, etc. Even just for a while to (a) get used to not smoking with other people who are doing something and not smoking, (b) doing the other activity - something you potentially could or do enjoy, and could be something you could get into, and (c) maybe meet people who don’t smoke. I know if you keep hanging out with people who smoke, all the time, it could be hard.
I don’t know if these ideas will be useful, but I wish you success. My lungs thank me.
Oh, and my mother died of emphysema and lung cancer, she smoked for 60 years.
