Issues with GERD

I am a relatively healthy 69 year old male who has had bouts of gerd (acid reflex) in my life. I've had several endoscopy"s done, most recently January of 2022 diagnosis of Gastritis. I don't smoke and drink in moderation socially (not a lot). Recently I developed my worst symptoms ever, not sleeping very good ( I have elevated bed),very bad pressure in chest which creates tremendous anxiety making it had to breathe and catch my breath, floor pacing...terrible stress on body. Oddly enough it's been worse every other morning when I wake up. I take Protonix and Pepcid, Mylanta and I just got some new stuff called Nutrasec, a tablet like Tums only better that you take after eating that helps a little. I was cruising right along until 10 days ago the it hit me like a tank. I gave up coffee and changed my diet drastically and am trying to schedule another endoscopy. I'm hoping maybe my esophagus needs stretched or I'm a candidate for esophagus sphincter surgery. I feel beat and it sucks trying to sleep on my left side all night. Anybody out there having similar problems?
