I spent twelve days in the Amazon rainforest attending an Ayahuasca retreat where we drank the brew on seven nights. It was both the most difficult and the most therapeutic experience of my life. In part 1 of this blog series I discussed some preliminary considerations regarding Ayahuasca, and in part 2 I discussed the preparatory diet. Here in part 3 I'll be discussing dosages, and the physical effects of Ayahuasca intoxication. (The video version of this post can be found here.)
