I know you said no ibogaine, but I was addicted to opiates for 10 years (not heroin though I have been addicted to heroin twice). I tripped a lot throughout that, sometimes with the intention of getting insight into my addiction. The behavior never changed and it got worse and worse. Recently I did an ibogaine flood dose and the transformative power of it has been so startling and amazing. For the first time I am off opiates and really happy about it. I'm also doing the work like going to counseling, eating right and working out (all of this after the ibogaine). Feels like a lot of things came together in my head. The way it works is totally different from other psychedelics, it's more of a dream vision quest that for me seemed really random until afterwards. Of course the commitment with ibogaine is a lot more because the flood dose lasts super strong for 3 days and then there is a reintegration period. I did it at home but it's hard for me to recommend doing that as a lot could have gone wrong (I was dreaming while awake on the 3rd day, and straight up immobilized for the first 2 days. That 3rd day I thought I was with it but I was not, whatsoever, ie, I didn't even realize I was dreaming while awake with only brief periods of lucidity). It was an amazing experience though, one of the least frightening psychedelic experiences I've had and also one of the best feeling.
