Do not eat more than one serving of York sugar free peppermint patties. I couldnt find the gas warning on the package when it was full, but ha it magically appeared when it was empty, after 3.5 servings. I spent the rest of the day running to the bathroom. The good news is, usually after 3 such trips my butt is on fire. I must have healed it? Maybe i can have a colonoscopy after all. Anyway, i also lost another lb. To the terlet.
