I've been taking metamucil for something like 25 years now. I take two heaping tablespoons a day, and a third spoon if I'm flaring and having loose stools.
I find it helps bulk up the stools and it makes them easier to pass. My GI years ago had recommended it so I'd "never have to strain again" and I have found that to be true.
When I need to go off it, as for the 5 days pre-colonoscopy, I find my stool smaller, less well-formed, and I find myself involved in the sort of involuntary spasming/straining.
My son's GI recommends Benefiber, also.....
