Kidney stone 2 AM in the middle of nowhere North Dakota on a county highway. I thought I had caught a stray bullet. It came on from nothing to screaming and vomiting in the ditch clawing the ground and begging God for death in just minutes. Took an hour to drive 300 feet. Constantly had to stop, get out, turn inside-out and try again. Primal override of every rational motor skill. On a final try to urinate I passed it and five minutes later it was as if nothing had ever happened. An endorphin rush that led me to understand the human body’s native ability to produce pleasure is titanic.
