Damn well one of the most beautiful experiences of life is a flood dose of ibogaine, surpassing ayahuasca & LSD in its rejuvenative ability. Not being able to move for hours gives you either claustrophobia if you are of that temperament or extreme comfort. I alternated between the two, primarily leaning towards comfort. With an MAOI (5-7g ground syrian rue) in the mix it tended toward claustrophobia presumably due to the SSRI-MAOI interaction between iboga and rue alkaloids.
I agree with "iboga is a psychedelic mount everest" and this is coming from someone who's taken 60-90g MHRB in one hit (ravaged by the light is the best way I can sum that one up).
