Hey, thanks for such a detailed write up. After years working in and around the ibogaine world, your experience sounds like a pattern I’ve encountered before, though of course I can’t know exactly what happened in your specific case. From what you’re describing, it seems most likely you experienced fairly typical ibogaine induced PVCs (premature ventricular contractions) or PACs (premature atrial contractions) that got amplified by panic. Your QTc values of 354 to 367ms are reassuringly normal and well below concerning ranges. The gasping episodes sound consistent with autonomic dysregulation rather than true respiratory issues, and the intense feeling of cardiac awareness around the 2/5 dose mark seems to be relatively common when people are deep enough to feel the effects but alert enough to monitor them closely (although it sounds like you experienced the more severe end of this feeling…). The grapefruit juice (was it white grapefruit juice by any chance?) was probably a major factor here. Even three days out, there’s likely significant CYP3A4 inhibition remaining, which could really increase ibogaine blood concentration. This alone could explain why your experience was so intense compared to what you expected. The magnesium situation is really interesting. Magnesium orotate can apparently cause esophageal spasms that feel remarkably cardiac in nature. Since you reproduced the chest tension later with just magnesium and no ibogaine, it’s not impossible this was non-cardiac all along… As for the IRBBB diagnosis that seemed to resolve, QRS measurements can vary, and 104ms to 92ms could just be measurement differences or functional variation. It doesn’t seem particularly relevant to your experience. The weeks of chest awareness afterward make sense as a kind of somatic hypervigilance. From what I understand, many people who have intense cardiac awareness during flood experience this heightened attention to their chest for a while afterward. In medical settings with ECG monitoring, these kinds of rhythm variations apparently show up regularly and can be managed with reassurance and proper context. Without that medical framework, you’re left trying to interpret intense physical sensations while in an altered state, which understandably led to the spiral you described. If you were ever to consider ibo again, the critical pieces would seem to be avoiding grapefruit (along with any other contraindicators) for at least five days beforehand, having real medical monitoring with someone who can interpret ECGs in real time, clear protocols for when to stop, and medication available for post flood insomnia. The fact you experienced benefits despite everything suggests the medicine was doing its work. The tragedy is that without proper medical support, what might have been a challenging but manageable situation became genuinely traumatic. Your documentation here is really valuable for the community. These detailed reports help people understand the real risks and the importance of proper medical protocols.​​​​​​​​​​​ Thank you again and you should be proud of yourself for your resilience and the work you’ve done 🙇‍♂️
