Having potent cactus helps. 125 to 200 mL for an effective dose isn't that bad if the salts and mucilage aren't too concentrated. Boiling down cactus brew can be very time & energy intensive - there are arguments for minimizing this.
Embrace the flavour!
“There is a way of manipulating matter and energy so as to produce what modern scientists call 'a field of force'. The field acts on the observer and puts him in a privileged position vis-à-vis the universe. From this position he has access to the realities which are ordinarily hidden from us by time and space, matter and energy. This is what we call the Great Work."
― Jacques Bergier, quoting Fulcanelli
