I suddenly started having terrible acid reflux. It got so bad one night that I thought I might be having a heart attack. I started taking omeprazole. Took it for 1 month. The MINUTE I stopped it was right back where I started. Long story short, after searching the internet, I started eating 1/4-1/2 of and apple (just the sweet types, not tart) a couple of hours before bed. The next morning I woke up with no heartburn!! I do this every evening. If it's not convenient, or I'm just not in the mood I have a little applesauce. Also, I switch up with 1 1/2 teaspoons of Raw, Organic, Unfiltered honey. Very soothing whenever you just need a tweak. Please try it.
Judging from your symptoms, it is possible that you may have hiatal hernia or an issue with the tone of your lower esophageal sphincter. Both of these can cause acid reflux that rebounds as soon as you stop antacids. Definite diagnosis can only be made after further investigations such as endoscopy or imaging. Several clinical trials are ongoing to find safer non-invasive methods to treat acid reflux.
