On a related note, I can comment that the yogurts with live bacteria certainly help with reducing gassiness in the body. I suffered badly from burping and trapped wind while I was pregnant, saw that someone had recommended eating these yogurts, and bingo - it worked! So - it might well help reduce smelly bedrooms caused by gassy SO's!
Now if I could persuade my DH to stop stealing the duvet and sleeping on top of it every time I go and settle DD during the night, so I have to fight to get back into bed, I'd get an extra 10mins or so sleep every night!
