I took fake acid (some NBOMe probably), is taking quetiapine to mellow it out a good idea or am I screwed?

Don't know the fucking dosage nor what it is. Trusted a friend it was LSD. I took half a tab then redosed but spat it out. It's been like 12 hours and it's not wearing off at all. I just want to go to sleep or at least get that shit out of my system.
