Combine that with only doing "allergy" doses first (think, peanut dust that would trigger your throat to swell, but not close as if you had taken a spoonfull of peanut butter), and you really will be okay.
As a pro tip I tell everyone exploring lsd/shrooms - always have a benzo on handy. If you need to end the trip NOW, it'll almost for sure do the trick. If you may be susecptible to mental trauma, you will be doing no one a favor by "pushing through" it.
Message me if you want :)
During a trip I lived what people describe as an "ego death", where I saw myself disappearing and dying, and it was the most frightening experience of my life. Not only was I completely unable to take a benzo at this point, but it is very much a death and rebirth movement as described by Leary in the psychedelic experience. If I was pulled out from that movement without completing it, I don't know what would have happened. I think I would have been left seriously shaken and disturbed. It was crucial perceiving myself coming back to existence in order to feel "me" again.
Sometimes "bad trips" aren't "bad", they're learning experiences meant to be completed, even if it is tough.
