I have been taking omeprazole (Prilosec) every other day for the past ~15 years. What a godsend. Before that I was popping Rolaids 3-4 at a time all day every day like candy. I also eat too much junk food, I am sure that is part of my problem. I don’t know about bacteria in the gut, I don’t think that is really my issue. It’s just from an overactive stomach pumping out way too much acid. It runs in my family too, my dad and siblings all do the same. Spicy, oily, and acidic foods all affect my stomach. Tomato sauce, peppers, deep fried foods, soda, CIDER, etc., those are the biggest culprits. I drink far less soda than I used to, as it started to cause other major digestive problems. I can have one soda a day, but two is bad news. Oddly enough, beer does not give me the same level of grief, thank heavens.
