If you drink alcohol regularly, it'll be the root cause. Just stop.

To stop acid, mix a quarter teaspoon (or more, but no more than a teaspoon in total) of baking soda with just a small amount of water. Think about an ounce or less. Have a glass of regular water ready to wash out your mouth. Drink a few ounces of regular water to "chase" the concoction.

Be ready to burp. A lot.

Beware, baking soda has a ton of salt in it.

Good luck

Remove the acids from your diet. Stop eating spicy foods (like jalopeno) for a while. Cayenne is okay. Don't drink before you eat. Investigate ox bile.

Congees (rice soup) work right away.

The starch will coat your stomach walls and help rebuild its natural mucus.

Don't eat after 5 p.m (absolutely never eat before bed). Get used to sleeping with the head of your bed elevated at about 45 degrees. Use a product called Gaviscon, it's similar to Tums but works better for reflux. Start taking something like pepcid or one of the proton pump inhibitors. Lose weight if necessary, that will work wonders in and of itself. Ideally talk to your doctor about it and get tested for how bad your reflux is.

Reflux is a serious issue and can eventually lead to esophageal cancer. It can be managed well with lifestyle changes but it's not something to ignore.

How is your digestion overall?

The most helpful thing I've found is avoiding tap water. I end up with a major acid problem when having sauce from a Japanese/Chinese restaurant (I'm assuming they used tap water) and when I tried using the "filtered" water at the gym.

Munching down a couple of extra strength antacid tablets takes care of my indigestion 98% of the time. A glass of cold milk neutralizes my heartburn 60% of the time. Restrict hard liquor. That is what gave me the most heartburn in my life, the most intense and relentless heartburn events in my memory. Since restricting hard liquor I seldom get heartburn anymore, maybe once or twice a year ... and OTC antacid kills that if milk doesn't.

Not eating within a couple hours of bed

Smaller meals

Adjustable base for your mattress (this works best)

More salt in your diet as our stomach acid is derived from salt, acid reflux is caused by salt deficiencies at its core. And yes salt is bad for you especially if you’re stagnant, it causes inflammation which can be alleviated with an isolated grounding sheet for your mattress. Emphasis on isolated ground, I have a grounding rod right in my closet with my sheets hooked to it. Unplugged for thunder storms, because I don’t want to find out.

Not cheap, goods I mentioned is gonna run about a grand all-in. Pay ultra - attention to EVERYTHING between you and the ground; tires, shoes, mattress, bridges, planes. Acid reflux is carcinogenic, so be careful.

Edit: autocorrect corrected

Check your blood sugar. High blood sugar often causes acid reflux - something the “medical professionals” don’t want you to know until it’s too late and you’ve burned out your body and they can keep you on meds forever.

Yogurt really helps me, enough that I stopped taking pills. I eat "Oui" brand vanilla. Different brands have different cultures, some brands are dead. Just eat about one jar per day, or every other day if you need to save money.

Odorless fish oil, taken with breakfast reduces pain and discomfort from the acid and also the rise of the acid.

Sleeping on your left side is a bit of a mitigating factor, raising the head of your mattress is also a help or just adding pillows to angle your torso and and throat better against rising acid.

Alcohol and over consumption are the simplest fixes, theoretically.

If you have trouble cutting your food intake start drinking electrolytes, move away from simple carbohydrates, cut sugar to under 10 grams in a day with none in your final meal. Make sure you are eating something with a comprehensive supply of amino acids, if that's just soy sauce on brown rice or a full amino protein powder you'll be fine.

Most people with reflux over consume, usually it's because gut flora are confusing you with hunger signals or various chemical signals to make you feel shitty if you don't feed them all they want, they can dump signaling compounds into your body to manipulate you and your hormone responses to food. The stuff in the above paragraph works to sate them and cull the populations driving you to over consume.

I had to make those changes to my own diet for a different medical reason but my reflux disappeared and I could be satiated by roughly 1/3rd as much food at any given meal.
