I boiled down the san pedro in a crock pot for 24 hours on high, and 12 hours on low. Then I used a cheese cloth to seperate the pulp, and then boiled down the remaining tea until I had 4 oz. I started with 1 lb (18 inches of 2.25 inch diameter) of raw cacti, removed the woody core and waxy skin and spines before cooking, and here's what happened when I consumed it: Within 1 hour my mood changed to "very happy", and I had a tingly sensation all over my body. It felt like a small dose of "X" (quarter pill), but I had no sense of tripping like I had on shrooms. I was with my girlfriend, and we had some of the best sex ever. The sex also reminded me of "X" only better. So, I know I had some mescalin in my system, but probably not much. Anyway, because of the sexual experience, it was totally worth it. I will probably do two feet and cook it down for my next dose. Scar
