It is not "normal". The gall bladder stores bile, which is produced by the liver, to help with the digestion of fat. Remove it, and it can cause problems with that digestion from lack of bile. Also, you can develop "bile dumping" where the bile has no where to go without your GB, so you get TOO MUCH bile.
My first guess is that you may not be getting enough bile. One solution to this is using bile salt tablets to replace the bile your body is no longer providing enough of. However, the lack of bile also could be cause be sphincter of oddi dysfunction. Basically the valve that regulates the bile coming into the digestive track is not working properly and you don't have enough bile coming into your intestines. But this most often is associated with "gall bladder attack like" symptoms as the bile is back up in your billary tree. Also a low fat diet can help to improve this issue quite often.
If its too much bile, a drug called cholestyramine (Questran) can be used. Sometimes along with .Imodium. Questran binds with the bile salts and slows down their move into the large intestine, where they actually act as a laxitive. Imodium slows the contraction of the small intestine so food doesn't go thru you so quickly.
Ask your doctor about these issues....
What do you consider bland food?
