Hyoscyamine
"After undergoing numerous tests with no definative diagnostic answers and under the threat of another CT scan followed by another Colonoscopy, my physician suggested trying Hyoscyamine Sulfate - an anti spasmodic. I picked up the perscription, took one of the very small tablets and LITERALLY within 15 minutes the spasm's ended and the pain subsided. WHY didn't someone try this therapy when I first had symptoms 30 years ago??? Within the past week, I've had only 2 spasmodic episodes each curtailed within 15 minutes after downing a single tablet. The only other medication that I've experienced work this effectively and fast for anything has been tumms for heartburn. Bravo - finally a working solution. No side effects noticed after 3 doses."
