diarrhea
"I have been battling diarrhea for over 10 years.  My GE doctor prescribed asacol, vsl#3, and xifaxan.  I took all in combination and had almost instant relief.  Then I stopped taking the prescribed drugs for 6 weeks and the symptoms started to return. I resumed taking vsl#3 and asacol with mediocre results.  I then added xifaxan and my bowel movements returned to normal. I wonder how long and how frequently I will have to take this drug before I am permanently cured of this condition."
