You eat a bunch of peyote before the show

You score several peyote chunks and you just can't wait till after the concert you eat them on the way to the show. Into the second song you start feeling it. You preform a good show but near the end you vomit onto the stage. You do a couple more songs as the trip begins to get hard.

  1. your handlers drag you off stage
  2. wander confused into the audience
