Hi, pinkblossom:
In most cases, I think that supplementing with Betaine HCl with Pepsin is supposed to be temporary. The idea is to provide short-term support and relief, while addressing the root cause of low stomach acid. Ultimately, the goal would be to help the stomach recover its ability to produce acid naturally. Long-term supplementing might be warranted, however, if one's ability to produce stomach acid is permanently impaired.
If you get a burning sensation when taking Betaine HCl with Pepsin, that might mean you already had sufficient stomach acid. Have you had a direct measure of stomach acid, such as with a Heidelberg Gastrogram Study?
Now, to answer your original question...
One thing that I think has helped my GERD somewhat is to raise the head of my mattress a few inches. The way I did it was to use a couple of the throw pillows from my couch and put them between my mattress and pedestal. Some people put a brick or a couple of two-by-four board under the legs of their box spring. Or, they sleep on a wedge pillow. Anything that helps lift the head a few inches above the stomach, so there's no backflow of liquid, if the lower esophageal sphincter (LES) isn't functioning properly.
I still have an occasional episode of GERD, but not often and it's usually just a day or two at the most. I've had it for years, no matter what diet I've followed. about
25 years ago, I took a prescript
ion Proton Pump Inhibitor (PPI) for a short while, but decided to stop taking it. I think it was Omeprazole (Prilosec) that I took, but it might have been Esomeprazole (Nexium). It was one of those two. I don't think I took it for more than a month or two. Back then, I was being prescribed several medications for several issues and quit them all out of frustration.
Just within the past three years, I started getting GERD when eating a particular junk food that I would sometimes buy. It was this product:

The only other meal that I've repeatedly noticed causing me GERD is when eating an excessive amount of a gluten-free pasta dish I make. It's brown rice pasta, a jar of low-sodium pasta sauce, a can of no-salt-added diced tomatoes, 12-15 cloves of garlic, a diced onion, onion powder, garlic powder, and some unsalted broth. If I have a bowl or two, I'm fine. But, when I'm really hungry, I tend to eat like a hyena and will eat three or four bowls, despite knowing full well I'm going to be miserable and wish I hadn't done so. I'm guessing maybe it's all the tomato products (acidic), but I don't really know for sure.
When I do have a flare of GERD, I usually try to eat a light meal. Sometimes that helps, sometimes not. If not, I'll go buy a 4-pack of Reed's Ginger Beer (non-alcoholic) and drink one somewhat "slowly" over 15-20 minutes.

all I have. I hope maybe something here will be helpful - or, lead you to something helpful.
Good luck,
Dude
