Yup, I agree with Hypoguy. Don't let them take your gallbladder out! Your issues sound WAY more like a gastrointestinal or stomach problem. I suggest you read all the links I gave you and start a bowel cleanse, with Liver Flushes every two weeks.
If they take the gallbladder out...then you'll have to deal with all the issues that go along with not having a gallbladder.
