Bile reflux constant pain, any way to stop this?

Hi, it seems this is somewhat specific condition I'm suffering from, at least judging from the internet, but I don't suffer from acid reflux like one has when suffering from GERD or gastritis. Instead I suffer from bile reflux and the pain it causes is becoming unbearable. Unlike heartburn, the bile causes me to be constantly in pain, burning my throat and esophagus. When I first diagnosed I was given Nexium and for a while it worked, but things are getting worse and worse. I'm losing weight because I can't even take bite of food - it causes my stomach to spasm so hard and it hurts through all day or night. My gallbladder is removed and I was hoping after that at least I won't be in pain all the time, but the bile relfux and the constant pain are completely draining me.
