Wear a Flatulence Deodorizer and not have any problems. Otherwise this is some good advice
Q: In the afternoons I often have very loud gas.
The Flatulence Deodorizer is made by Flat-D Innovations. It is an activated charcoal cloth pad that is placed in the underwear next to the buttocks. When smelly gas is expelled, the pad will absorb or remove the odor commonly associated with the intestinal gas or flatus. www.flat-d.com is the website.
