After 10+ years of acid reflux and a massive hiatal hernia making me absolutely miserable, no matter what I ate/drank, no matter how much I weighed, not matter how long I waited to lay down after eating/drinking, I had the Nissen Fundoplication surgery in October 2017.
This:
And while my stomach can now only hold 2/3 of what it used to, and there are a few dietary/behavior restrictions, I haven't had a single instance of acid reflux/GERD since, and haven't taken a single pill for it either. For anyone who's interested, feel free to PM me for more details, because there are lots of things to keep in mind, especially finding the correct surgeon to do this. You want someone who's done this hundreds/thousands of times. Not someone who can just stumble their way through it.
