hi, i've done shrooms lots of times. most of those times i did the shrooms alone (without any other drugs), but 2 times i combined weed with the shrooms. and each of those 2 times i ended up blacking-out (losing conscioussness). my friends tell me that i was standing in 1 spot for an hour asking what my name is. i dont even remember that. all i remember is the start of the trip, some insane visuals, then everything is really hazy and i only have fragments of random memories of the night. my question is, why do i black-out when i combine weed with shrooms? (i never black-out just on shrooms by themselves), is this common, anyone else experience something similar ? and how can it be prevented. i want to enjoy a nice trip, without any black-outs. is there any vitamins or something i can take to prevent blackouts ? Thanks a lot!
