Notes on the ritual
Hero partial
A hero with the benefit word in italic
Caffeine works by blocking adenosine, the signal that tells you that you are tired. It does not add anything. It hides something, and it hands it back later. Fungki has no caffeine in it, so there is no spike to ride and no crash to manage.

A note from Tonya
I started Rainbo because I wanted the mushrooms in the cup to be the dose the studies used.
Two teaspoons, a stir, every morning.
