Sorry I am so late, but wondering how this was going, or went?
I have personally taken iboga 2 times, once in a full on, heavy flood dose, of which for drug addiction, the proper dosage or treatment range is from about 10mg/kg up to 25mg/kg. More than 25 mg/kg has shown to damage punjike cells in rats' brains, but I am not sure about humans. There may be some studies on primates if you search really well.
My second dose, involved the simple acetic acid extraction and I vomited up the majority of the dose too quickly, and didn't feel like extracting the vomit, however, considering the price of a single dose, I definitely would in the future. I extracted 44 grams of quality bark, this way and took half, but threw it up as soon as the capsules busted open in my stomach. The remaining extract I ate over a period of several hours and I had trails, tracers, and ataxia for about 48 hours, but was able to function. I even walked to the corner store while under the influence.
It was interesting but not a heavy enough dose to combat all the opiate withdrawal for which I had taken it for, but it had lasting after effects for weeks, and did help me reduce my opiate intake (as well as made cigarettes taste extremely horrible for weeks, if not months). I will be journeying again soon, and have enough for at least two flood doses, so I will not be dosing too low this round, however I will still be very cautious.
I have a bit of experience and have studied ibogaine since about 2003, and I feel comfortable taking it with a trusted sitter, but would not recommend this for a first timer, or someone that hasn't done extensive research and study into proper dosing protocols, plus possibly having a trained nurse or EMT on standby, that has been informed of many of the precautions necessary for undertaking such a powerful journey.
I do have loads of information I could present, but it is information that I have gathered from over 7 years of study of the plant and it's alkaloids, but finding and noting every reference will be very time consuming, if even possible, so I will do all I can to help, but it may take me awhile to answer all relevant questions and can only speak of my own experience, from the studies, and lots of anecdotal experiences from those (treatment providers) very involved in the ibogaine movement. I will specify what I know from experience, and what I understand from my studies.
Hope this helps someone!
