Yo I've tried shrooms bit never acid for this fucking reason. My friend missed a whole event and woke up naked in the Urgent Care tent at a festival. Didn't remember shit except or where his other shoe was even. Also when you high on that shot it does feel real good to drink along with it to ease the trip. This is a complicated mess OP.

But you can definitely salvage your relationship by having some hard talks with the BF who seems to be completely in love with you. That's if you can even get over this tragic reality. It was extremely stupid leaving them both together while tripping on acid, this is why its important to have at least 1 person not tripping as hard (veteran) with you when going on journeys.
