NPR did a segment on Laryngopharyngeal Acid Reflux Disease that offers a different approach for persons not responding to the usual antacids.They mentioned a specific product, Reflux Gourmet, available from Amazon.

“Antacids like Prilosec help about two-thirds of patients, he says, but some people don’t respond to them. In recent years, doctors have switched to recommending medications with alginates. Made from brown seaweed, alginates form a raft on top of a patient’s stomach contents so the liquid can’t travel up to the esophagus or throat, he says.”

“ Gaviscon heartburn relief tablets and a new product made in California called Reflux Gourmet contain alginates. People can’t buy a more effective Canadian version of Gaviscon in U.S. pharmacies yet, but it’s available on Amazon, he says.”

My mother often had esophageal spasms caused by reflux that could interfere with her eating and maintaining a healthy weight. A gastro specialist ordered liquid prilosec at one point (she had trouble swallowing pills that shouldn't be crushed) and her PC quickly nixed that for potential side effects. Her PC started her on 10 mg famitodine (Pepcid AC) morning and evening. We were already aware she shouldn't eat late in the evening, and had the head of her bed slightly raised. We'd also bought a wedge shaped pillow.

That worked in her case. Many of the OTC famitodine are 20 mg though as are all of Costco's so I had to order them from her pharmacist. She really was better with no side effects determined, and manged a steady monthly 1 1/4# consistent weight gain her last two years of life. The Kaiser nutritionists had told me to never expect a gain and to be happy with no more loss.....she surprised us once again 😁

YMMV....this is only one example and mother more advanced in years than you are.

My sister suggested that I keep a food diary. Your onion experience now makes me think it is a good idea. I just know I'm really uncomfortable. I'm also stressed out and tired and kinda unhappy (long story) but I'm working on it.

Generic version of Prilosec every morning has worked well for me. My #2DD was diagnosed with GURD. She had an operation vs drugs given she's in her 20s.

I had chronic reflux for years, had the scope procedure and everything. I went from pepcid ac to prilosec plus tums. It was awful.

I finally did the Whole30 cleanse. I cleaned my whole system of chemicals, sugar, everything that was deemed inflamatory. I still had the reflux. I continued analyzing the food and it turns out I had two main culprits causing the whole issue. My daily black coffee and onions! My favorite vegetable, go figure. Red sauce also makes it act up.

I switched to making a cold brew concentrate coffee that I mix 4oz coffee and 8oz water and heat it in the microwave. And now I only eat onions selectively, knowing some discomfort will ensue. I also learned I am way, way more lactose intolerant than I thought.

I highly recommend a food cleanse and then a system check off the meds. I have been medication free for years now.

I knew I had problems with garlic. I just didn't make a connection. I can eat Shallots and spring onions in small amounts and leeks as well. I just don't over do. People vary in their intolerance to the chemicals in the family. Remember that it is hard to find processed food that doesn't have dehydrated onion and garlic in it so Jarred sauces and frozen pizza and so on. I was eating tums all day. I kept them around all the time. I loved cooked onions in my food. Cutting out onions was literally an overnight cure. I have also more recently developed intolerance to watermelon of all things. That makes me vomit. I adore watermelon. Dang.

Not me, but a friend has the issue and has found relief by cutting way back on sugar. I had issues with acid stomach and reflux as did DH when we were eating eggs daily for breakfast. Eggs have a long-chain protein which can be difficult to digest. We now eat eggs only every 2nd or 3rd day and have no issue. So sounds like the dietary route can be a helpful one. Some other common culprits include alcohol and tomato products, especially in the evening.

I've had acid reflux for a long time and I'm not sure if it's mainly food related but some things have helped, such as when I do eat spicy foods that are loaded with tomatoes (like chili & spaghetti) I'll take a Pepcid AC before eating and that helps. I also elevate the head of our bed about 4", there are bed frame elevators for this purpose, and chew gum when gardening ( involves a lot of bending over) which helps. A Big Help was to eliminate all internet activity after dinner ;-)
