I'm planning to quit smoking all together in the next few days.any advice/help/ressources

So I smoked for 6 years, the last 4 years or so I smoke about a pack a day (20 cigarettes). I have quit smoking cold turkey for 8 months from November 2023 to July 2024. I had the decision after along streak of smoking more than a pack a day, feeling always ill, and hating smoking. I've read Allen carr book and just quit. In July I had a period of emptiness, void and feeling lost. I got back to smoking and I wasn't able to quit since despite numerous attempts.

I'm planning to give another try, and I'm set to make this one successful for ever. So any advice, recommendations, sources, habits, routines, whatever it takes.

I found that easing myself into it doesn't really work, also I can't afford patches and similar stuff (I live in a third world country where these things are way more expensive that cigarettes)

(I'm currently reading the book "this naked mind)
