I tried acupuncture and it did nothing for me. I think that if you have terrible GERD then it's not enough to try herbs or cider vinegar and the like. Apparently, bile reflux is common after cholecystectomy. See details and treatment possibilities here: https://www.drmalladi.com/acid-reflux-after-gallbladder-removal/
Maybe you also have a hiatal hernia that is keeping the LES open. (I don't know if you've written more details ab out your situation previously, so apologize that I didn't see it.)
You should go to a gastroenterologist and see what they suggest. Maybe they'll do an endoscopy to see the situation. (With the sedation they give, it's a relatively easy procedure.)
