I have the answer for you. I also had my gall bladder removed years ago and had the same urgency problem. I now take a very inexpensive med called “colestid”. It absorbs excess bile in the gut that is making you have to rush to the restroom after meals. I also take no less than 6 fibercon a day. I know this sounds like it will only make things worse, but it actually helps to also absorb the excess bile spilling into your gut because you have no gall bladder to control it. ask your doctor about Colestid, it is a cholesterol lowering drug which is also given to absorb bile,,,, good luck
