Can I ask where you stand on the value/lack thereof or efficacy/inefficacy, safety/hazard potential of the Choline Dioxide - or is that a topic you'd prefer to avoid? If so, I surely understand.
Have you tried Homozon or any other means of oxygenating? I'd think Homozon would be very helpful to you, given your comments regarding the intestinal issues/sinus connection. I've never really had to deal w much intestinal probs - probably because I either don't eat or when I do, I pretty much only eat fiber - but that stuff really obliterates things in the GI. More than I can take, most of the time - but if you have trouble "down there" it Could have a more appealing effect.
