It's not uncommon the ceremony centers in South America do 5-7 sessions if not more. I had a batch of it and did it over time. I had interesting experiences overall, some positive, some hard, but all in all it wasn't bad. I came to realize it wasn't going to be a cure for me. More so something that was interesting to experience.Wow, so why did you keep doing it out of interest? Was it a proper ceremony or centre?
