Have you ever been to the doctor to work out what the problem is? Do certain foods tend to set it off? Lentils and Cabbage are notorious for making out gut gassy. Have you tried probiotics? If you can find out what the problem is maybe you won't have to deal with this issue. An embarrassing question for you - are you constipated? Lot's of remedies for that. I have never heard of Beano as I live in another country. Maybe you could try it to see if it does help.

You never know - the guy might sleep straight through it.
