Benefits of Gall bladder Removal?

I had a gall bladder attack this past weekend. I went to the DR. today. I was sent to do an ultrasound. I have had all of this done before. I feel like I am just going through the motions again, and the real problem is that my Gall Bladder is diseased. What are the risks of leaving it in (it only functions at 2 percent)? Are there any suggestions on changing my diet vs having it removed? Can bile back up into the system and feel like acid reflux. I have had a foul taste in my throat since the attack. Are there any people out there that have had it out and are still having problems? Does anyone have a diseased Gall bladder, but are using alternative ways to stave off attacks?
