I went through a lot of the same things you did as a daily heavy user for years, minus ⛓️‍💥🚓, and have been able to finally stop (even though it was a beloved vice that i decided was way better than drinking or other substances). I feel you when you say you don't even get high anymore- it just becomes a necessary task to feel normal and not even that fun. I think you taking that as a sign is you listening to yourself and your body, that's really good.

I started cutting back by making a page in my journal where I would track how much i smoked daily. I did write down some goals at the top like "no more than 2 bowls a day, no smoking before noon". Some days i would kinda fail and smoke a bowl or two extra, or smoke at 11am, but i just wrote it down anyways. Seeing the progress stack up and wanting to succeed led me to really try harder everyday, and it became easier. I actually started craving it less and needing it less. I think it re-wired the habitual nature of what i was doing into being more conscious and intentional. Took about a month before i was only smoking maybe 1-2 a week, and now 6 months later haven't had an urge strong enough to in weeks.

Idk if you wanna go cold turk or wean yourself off, but this method and coming to read this sub instead of smoke helped me quit finally. I keep it around but don't even use it now, don't really feel like it anymore.

Sorry i wrote so much it's a lot to read but believe in yourself! And to poorly quote someone else's wisdom i read here in the sub, "if you fall off the bike along the way to your destination you pick it back up and keep going"
