My advice is to keep your stomache digesting fast, which requires high acidity. High acidity is also required to maintain the correct bacteria. I was on acid suppressors which I believe was more detrimental. Try to gradually get to a point where you have no need for any antacids.
As mentioned in my post: skip grains, nuts, fruit, (raw/too much) veg, milk, and don't drink close to meals (avoids dilution / overfull stomach). I found that beef/chicken is good but not mentioned often.
I had dizzy spells and was unable to sleep due to acid reflux and I am now practically back to normal. I just take care not to over eat.
