No, but I have friends who do and it's really cool (and very challenging).
Pollan is great! I'm a big fan of a lot of his work, but 'How to Change Your Mind' is one of my favorite books. I think that he's done a lot of good destigmatizing psychedelic usage for self growth.
I don't know if it's the right tool for everyone. But my first psilocybin trip was one of the most formative experiences of my life. It completely changed my relationship to food, and was the linchpin moment that a lot of my long term health improvements originally stemmed from.
