Ok let me first say that I am completely shocked. This is more a testimony rather than a new remedy but I'm just floored that something could work so quickly. I began to get a gallbladder attack about an hour ago after taking some fish oil pills. At least I think that's what caused it. So I looked online for remedies and found apple juice and apple cider vinegar can help. I ran into the kitchen and grabbed:

a cup of apple juice and
a tblsp of apple cider vinegar

and within seconds, about half way through the glass the pain ceased. I still have a little tenderness in the area of my gallbladder but this is such a lifesaver for anyone who has felt this pain. And since you're reading this I imagine you have. Not sure if it'll work for all attacks or if it'll prevent the pain from coming back but I'll see how the night goes. Thank you, thank you, thank you. :)
