Check out the Papua New Guinea episode of Survivorman, Les eats some. Give it a try and let us know how you make out. I can tell you that I did my first microdose experiment w/ psilocybin, and the focus was comparable to that of adderal...but way cooler, and natural, and focused. Could have walked all day.
