Suggest Treatment For Flatulence

I am having 2 major problems 1.     Flatulence 2.     The sensation of incomplete bowel evacuation (If I take medicine(ulcet/Mories) I donâ??t get this symptom) Flatulence: â?¢     Flatulence exists at all the times of the day even after complete bowel evacuation. â?¢     It increases when my anxiety (/stress/tension) increases. â?¢     Sometimes increases as the day progresses â?¢     I donâ??t have any pain in the stomach or abdomen â?¢     Sometimes I feel the gas formation near to the anus itself (may be in colon) , sometimes in stomach but many cases I donâ??t feel the gas formation, but there is emission of foul smell. It is very humiliating and I get very cautious about It and this intern increases the flatulence and makes me to avoid social gathering and meetings. I cannot concentrate in my work properly. I have been to many doctors but I didnâ??t get the cure. Some said it is acidity, some said IBS. They told there is no proper cure and to do regular exercise. I was told to stop taking milk and I have done that. I tried not eating potatoes, cabbage, beans etc. but it is not helping much. I feel I swallow lot of air, so I have tried to reduce it. Is there a cure for this? What should I do?
