post-cholecystectomy diarrhea
"Had my Gall bladder removed 12 years ago and have been using Questran on and off since. I use one packet a day in the morning and have reasonably stable BM, and stomach symptoms. I was taking it late at night for awhile but found that I was dehydrated and experiencing disturbed sleep with nightmares. Since switching to mornings, my sleep is back to normal. I don't believe it was the drug just the side effect. I also get nightmares when I binge on late night pizza with extra anchovies! 
I recommend this treatment to anybody who is experiencing persistant loose bowels with no fixed cause. I also love that my cholestorol levels are those of a fit 16 year old!"
