Does metamucil cause gas cramps?

Fermented...: Many fibers, particularly the water insoluble kind, are readily fermented by your gut flora. Some people have certain intolerances to bean husks (try beano), to wheat/barley/rye (gluten sensitivity), ;/or have a particularly active population in their gut of gas-forming organisms (try bifidobacter-containing probiotics). Maybe altered GI motility, ibs, air swallowing, maldigestion/malabsorption?
