Yeah that's true about ibogaine, it directly works on the opioid receptors. it blocks withdrawal during the experience and for me it seemed to perform some sort of reset, it truly felt like I hadn't spent years being addicted to opiates. I did it while I was still in withdrawal, but I had tapered down and switched to kratom and was most of the way through withdrawal already. I came out of it feeling no withdrawal for days, and then I felt mild lingering symptoms but I just didn't care, the thought of doing opiates to deal with it seemed like the dumbest thing I've ever heard. It did something really profound on a very sub-conscious level. The whole experience was a series of dreams, it felt like I got a deep reorganization of my brain. I came out of it ready to make big changes and I did make them. I realized I have the power to do and be whatever I want. It wasn't through some revelation either, like I said it wasn't really happening on a conscious level. It wasn't an epiphany, it was something deeper. The entire way it works is extremely different from classical psychedelics.
It's certainly worth a try if you've tried everything else. But be prepared to make some changes in your life afterwards because otherwise you'll probably fall right back into old patterns after a while. For me, I left a toxic relationship, and started doing things that made me happy. I rediscovered music and immersing myself in a band and playing live music gives me that deep satisfaction that we need in life. Without those changes, I don't think I would have had 5 years clean without even having cravings.
I relapsed eventually when my dad was sick and suffering, I made a mistake and unfortunately the addiction is back. But my life is still much better. Ibogaine was profoundly positive for me.
