Olanzapine vs Xanax tripkiller

First of yes I know Xanax won't kill a trip but im guessing it's going to dampen the anxiety a bunch. I have some olanzapine which I've read can completely stop a trip, but I also read a story where the trip got way way worse after they took it, which let to a hospital visit. I guess I could get some Xanax but that won't really stop the trip completely.

Does anyone have experience with LSD and Olanzapine?
