Bloating after gallbladder removed

I had my gall bladder removed in September of 2006, that's right 2 yrs ago. I immediately noticed bloating in my upper abdomen and was told that it was normal for a month or 2. It has been almost 2 years now and the bloating has not subsided AT ALL. (It does not "come & go".. It Stays) I was also told that walking & exercise would alleviate the bloating issue shortly. I work out 3 times a week and get plenty of exercise, and still, the bloating is a constant. It never goes down. Is there a miracle cure for this or a different approach that  can take....ANY advise would be greatly appreciated. THANKS IN ADVANCE
