I totally feel your pain.  I was in Florida for Thanksgiving about 2 years ago and I had a gallbladder attack, I thought i was going to die it hurt so bad. My sister had to take me to the ER, was there late after X-rays and sonograms,  They determined it was galls stones,  I was prescribed Vicodin for them... Got news for you once the attack starts, I think only morphine will take away the pain.  I ended up having my gallbladder removed,  no more pain!
