I know Asha and Rocky Caravelli, who operate Awakening in the Dream House (in Mexico)to be reputable, caring and responsible. As for cost, you may be able to come to a copacetic agreement through communication.
I'm guessing you're dealing with opiate addiction. That is a bitch. I have no experience with ibogaine, and what I've seen of it being used leaves me with an understanding that its only going to work as well as you do at recovery. I've seen people have a powerful experience, stay clean and then suicide upon relapse, possibly because they feel their addiction is stronger than whatever they encountered within the iboga-space.
If you go this route, realize it's not a magic fix. You may be able to outcome your withdrawal, but will you get to the source of your pain through it? That is the only way you will enter and remain in recovery. You must find and treat the pain.
In my experience, recovery was catalyzed indeed thru a powerful psychedelic event, in my case with 5meoDMT. This helped me to gain an expertsexperiential awareness of something far,far greater than me that i was yet an intrinsic and valuable part of. That alone was not enough. Among other things, I entered a methadone clinic, which is not something I'd recommend unless you have a demonstrated history of repeated failure to remain free long term of illicit use,but it's helped me. It's been over a six year haul full of work though to get to the place I'm in today, which is happy, free of illicits, and fulfilled. Addiction is a full time gig, so is recovery.
I put the credit forthat in the therapy, hundreds of hours in various self help classes and groups, meditation, volunteering, fulfilling work, friends etc etc. It's work, constant vigilance and perseverance, but worth it.
I've been where you are, it's a dark, dark place. You can be free. There's a few of us here on the nexus, you might find some like soulshere.
