I had the worst case of nervous stomach and ibs. I would fear leaving the house because I was afraid of having an attack somewhere that I couldn't get to a bathroom. Pepdo became my best friend.
We'll then a friend turned me on to psyllium husks and after about 1 month of using everyday, I don't have any trace of upset stomach or ibs.
I went to many doctors, who prescribed many tests and pills. Not one of them had mentioned psyllium. They didn't want to stop the money train from rolling in.
I think that many of the digestive problems experienced is most likely a lack of fiber in the diet and I would say try psyllium husk powder, it's worth a shot.
