Ya I think blueciel's results where there was psyllium plugging up the colon should be a warning about fibre. I read that fibre makes the colon work all that much harder to eliminate.
blueciel, I cannot agree about "fecal impaction" being my problem - the X-Ray showed different, and my Doc said "no, it is NOT fecal impaction on the colon walls". Thanks for your concern anyhow.
