My friend smoked some yesterday, average dose id say and i was really worried for him he started shaking really badly like he was having a fit and then he started being sick, wasnt full blown vomiting but he was heaving a lot and lots of stuff was coming out of him. He told me afterwards he was ina room hed been in before and these people were saying to him itll be ok just be sick, and he said in his dream he was crying a lot, so maybe it is like ayahuasca, where you physically get rid of pent up emotions ive yet to try the aya for myself though 3 failed attempts so far

as for how to handle the sickness i honestly dont know, cos it really was my freind lol Peace and Love
