Re RED (apple cider vinegar), after years of excruciating acid reflux and resultant sore throat, sleepless nights, expensive meds, I went online. Found this: In a cup of warm water (I nuke for ~45 seconds), add 2 tsp. cider vinegar. Add 1/4 tsp. baking soda. It’ll bubble. Stir. It’ll bubble more. Drink, preferably through a straw for your teeths’ sake. I do it after every meal, especially if high fat or spicy. Sometimes before bed, too. Haven’t had discomfort for months, since I started.
The problem may be your heart if you keep injesting baking soda! Baking soda will kill you!
Try a table spoon of dill pickle juice.
