Ah, the clench. A couple of years ago, a day at the range was followed by wings, onion rings, potato skins, and beers at Rooster's. 32 miles from home. Well, about halfway there, the sweats started. Then the urges. Cramping set in about five miles out. Hit the driveway at full speed, thankful that SWMBO and the kids were visiting her folks and I had the place to myself. Asked the doc about it later. He said a lot of people have allergies that make the rapid expulsions happen, a way the body protects itself. Some salad dressings will do it to me as well, especially some of the vinaigrette dressings with balsamic.
