Hi Zark
According to Sinclair, you should avoid the same things for IBS as for AS: in a nutshell, starch! everything else should be fine.
Also, I was thinking I might give the hydrogen peroxide thing a go... It still seems a bit drastic, but I hear what you say about water at Lourdes, etc, containing the same levels naturally (and I could certainly do with some water with 'miraculous' properties at the moment!). I've been into a few chemists and they only appear to stock the 6% stuff and look at me like I'm mad when I ask if it's food grade! In what kind of shop do you buy yours?
