Digest bitters. I take them from a company called Gaia.

Betain HCL Pepsin gets put out by many companies. I like Pure and take it the way I said.

You need to help your microbiome recover from years of PPIs which destroy them. How? Zinc carnosine (for gut lining). Bone Broth, preferably home made. I posted a simple recipe. They are easy to make and excellent for healing the gut and microbiome. Bio Gaia Gastrus for Optimal Gut Health.

NO Sugars! NO Artificial sweeteners-- all of them, even Stevia, mess up you microbiome. You can't cure GERD with a messed up microbiome.

No alcohol, until you fix the GERD.

Try to have you last meal of the day before 6 pm.

Try to loose weight. It makes GERD far worse. How? DO NOT COUNT calories. Instead go long periods during a day without eating. Try a schedule of 8 hours a day only eating and AT LEAST 16 hours without eating. You can have teas...herbal, ginger...even green. I now often eat only once a day, with kefir + flaxseed +chia + hemp hearts+chlorella or Spirulina for breakfast or as my first meal of the day at 12 or later. Have your last meal and eat to satiety.
I lost 40 lbs that way and it was a breeze.

Stay away from all processed foods, pre-prepared emulsifiers (they kill the bacteria in the the gut). Avoid simple carbs (pasta, rice, breads...I still eat potatoes for the potassium and love them roasted with olive oil of duck fat).

Stay away from all seed oils like canola, safflower, corm, peanut. They are "manufactured with chemicals and not cold pressed. Use olive oil, butter, duck fat, even lard believe it or not is better for you than seed oils.

Eat things like sauerkraut (no sugar added!) kimchi, kefir (plain no sugar, sweeteners etc which destroys all the benefit, Greek yogurt...NOT no or low fat or any sugars or fruits added.

I have NO confidence in most practicing Western physicians. Most know little and care less. The guideline on most things treat symptoms badly, make money for pharmaceuticals, often make things worse and never ever cure anything. Why kill the goose the lays the golden eggs? If I were a warrior shot up in battle, modern Western medicine would come as close as I could get to live to fight another day. Chronic anything. Fugggethabouit. So no, it would not occur to me to ask or care what my doctor thinks about any of the things I do to take care of my health. I just like to watch their amazement as my markers keep getting better and I keep getting older. The thought of having any doctor "approve" of what I take (other than my oncologist) makes me laugh. They come to me for advice on aliments they have no clue how to handle. i.e. magnesium from coconut water for night leg cramps. Most have had a few hours of nutrition in med school at best and have been taught that a calorie is a colorize is a calorie and it doesn't occur to them to say: Wait a minute. If you eat the same number of calories from donuts as salad or steak it has the same effect on body and metabolism you say ????? Some are beginning to wake up...but still too few.
