You don't want to try alternative diets when your gallbladder is so painful. You could be facing serious problems when having it removed now is a day surgery. I was in and out in half a day, took one pain killer, never even needed the rest.

... but meanwhile read gallbladderattack.com.

Just don't let it go into a further stages of pain, in fact, it sounds to me like you really should be talking to your doctor.
