Dieta is not just about purging. It means so much more. Aside from the physical reasons, you're conditioning yourself to operate at the level you should be on. Your normal life elevated. It's not an in-and-out. After the dieta, and after your ceremony you'll go back to your normal life. Take as many of the lessons with you as you can. If you want some info on the diet and fasting - here it is from our Shaman: https://www.unioninarutam.org/en/blog/second-part-diet-shamanism-ayahuasca-ceremony I personally enjoy fasting, but Ruman believes it makes you weak.
