Box office symptoms and conditions

I took this before going to the movies. Halfway there I could barely drive. The streetlights were glowing in a strange way. My heartbeat felt strange and my face itched. By the time I parked my car and ran towards the box office (late), I felt like I was floating. In the theater I saw people in front of me, talking. They faded away because they were not really there. I felt horrible, I felt dizzy and the floor was spinning. I stumbled to the bathroom and almost threw up but couldn't. I dragged myself to the counter and bought a soda, which tasted horrible but which I forced myself to drink. I was gasping and the world was spinnning. All in all it was a hellish experience. I will never take this drug again. It also did not get rid of my neck pain.
