Ken,
It sounds logical to me although there is a weak point: Will any heightening of your immune response also heighten your AS symptoms? For instance if you catch a cold or a food poisoning, will that have negative effects on AS?
What I also still wonder about: With which probiotics did you have negative effects and then especially which strains of bacteria where in there and did it contain fos?
