Smoked a crushed up ecstasy pill in a bong, the bong was obviously loaded with a huge hit of resin, I foolishly believed that the ecstasy wouldn't work if smoked (I know, retarded beyond believe, but in my defence, I was young and naive).
My resting heartbeat was 200 and stayed there for two hours. I was sat by a phone box (they existed in those days) just in case I needed to call an ambulance (again, totally ridiculous logic). Whilst I was there, I witnessed a drunk man walk back from town and get into the phone box, phone his recent ex and profess his love for her. She clearly wasn't interested, hung up on him, he puked in the phone box before exiting and then fell to the floor and pissed himself.
It was at this point I decided: "fuck it! If I die, I die". I walked back to my flat, cracked one off to a classic edition of Playboy and went to bed.
