For me, it's not tooting, it's belching. If I'm laying down and I sit up, I belch. If I'm sitting and I stand, I belch. Every time I change position, I belch. I have no control of it whatsoever. Every once in a while I'll
open my mouth to say something and... buuurp! I'm an Office Manager, and I answer the phone all day long. So far I've been lucky, but I'm waiting for the day when I'm on the phone with someone important and let one rip!
