Re: Bad Pain and alternating between...
Psyllium is a water soluble fiber-- the active stuff in Metamucil. It absorbs fluid and bulks up the stool. The worse person that I have ever known with explosive diarrhea was cured using Metamucil. That was 21 years ago and every since then I have taken psyllium and my wife takes it in a capasule form -- I use Equate from Wal Mart twice daily and my wife takes 880mg caps from the Vitamin Shoppe.
I know everyone responses differently but your loose stools could have been caused by intolerances to one or more trigger foods. Evryone that has IBS -- I read somewhere has 1 or more foods.
I have found that the doseage has to be right for each of us because we all have different daily diets with various amounts of fiber in them!!
