@pleonasm - That's good to know. One of my medications causes excessive flatulence which I'm finding really irritating. It's not painful, just embarrassing. I have discovered, though that if I go for a run that tends to clear me out for a while, I guess because the vibrations help or something.
I'm also trying not to eat many foods that are supposed to cause flatulence. Apparently it's got a lot to do with how much sulfur is in the foods you eat.
