I'm sorry to hear that you are going through that - it must be really frustrating! Have you been to many doctors about the problem? I wonder if it oculd be some sort of infection (bacterial or fungal)....
I'm sorry I don't have much experience with that exact type of odor, but I can tell you from what I have tried that chlorophyll, and good brands of zinc and magnesium have seemed to help me with some of the odor (at least, before I did the rinse). And if nothing else, the mkagnesium and chlorophyll definately kept my bowels on track!
