i usually do alcohol extract. the first 3 trips were mild doses, about 50 dry grams of peruvian torch dried green flesh (under the waxy layer).
i didn't throw up from any of the light doses. the time i did an extract from 100 dry grams i got sick and about an hour and a half into it, i threw up, but it felt like the right thing to do at the time, so i didn't supress the urge. i was sweating a LOT too so it was like my body was ridding itself of toxins in more ways than one. despite throwing up it was a beautiful experience. i felt a strong sense of peace and well being for the next month or so after the experience.
I've never tried actually like extracting the chemicals from the cactus, I just cut it up and blend the cactus spines and all in a blender with 1 part cactus to 1 part water, and then bring it to a boil in a soup kettle and then let it simmer and evaporate off as much of the water as possible, and then strain it through a clean white tshirt or something (NOT CHEESECLOTH DO NOT USE CHEESECLOTH) and then drink the resulting brew. I usually do a test run of it as soon as I've made it while its still warm, just to see how potent it was, and last time I did that, 4 fl oz of liquid gave me as nice a trip as my very first experience with the drug, so I decided to drink like 12 fl oz one night. I would imagine the dosage was upwards of 700mgs which is pretty nuts. That was the trip where I actually had open eye visuals and visual hallucinations on mescaline. It was about as intense as that drug can be, or as intense as I ever want it to be anyway.
GB: A friend of mine had a hookah, but he went to college, and its far away so I cant smoke with him anymore. (we used to sprinkle pot or salvia on top of it, that was pretty awesome) but yeah some of the hookah bars are really nice as far as like the interior ambience goes, they are clean, and they play middle eastern music, (one that I snuck into once is run by a Pakistani family and they actually play qawwali and I heard Nusrat Fateh Ali Khan so that was a++++) but the really trashy one that I hate lets people play their own music, which is always bad, or they play like egyptian and uae top 40 crap and it is painful (it basically sounds like our american R&B in arabic ugh)
