i have also tried the unsweetened apple cider with vinegar and it still bothers my throat and that is after my fundoplication, 3 dilations. my fundoplication is 1.5 years old. i still experience heartburn symptoms, with no help from antacids. I am getting an endoscopy today from my gastroenterologist today july12, 2018. I hope to know more about what is going on and why does drinking water make it seem worse.
