What Causes Abdominal Discomfort And Persistent Loose Bowels?

Hello doctor, I am manoj, male, 38 Suffering from prolonged diarrhea ( 6 weeks approx) I am having loose/watery sticky stools almost five six times a day, especially after few minutes of having meals. I can notice bubbles in the commode water along with some jelly type substances. Slight cramps in stomach are also noticed sometimes during the day but not always. I don t have any rectal bleeding. Gas passage is normal. No pain, yet uneasiness in stomach. Appetite is normal. There is no fever, no vomiting. I consulted doctor few weeks ago, during initial days of the problem who advised me NorfloxTZ twice a day. I took it religiously for 4 days and was sometimes feeling fine but sometimes not , that is, the stools were still watery having same problem. What it can be? Dear Doctor, please advise me a good treatment. I am worried.
