Occasional refux is manageable, but GERD is different. If you are a sufferer, lifestye changes work best: try to avoid acidic/spicy foods like tomato sauces and Italian or Mexican food- esp close to bed time. The same goes w/ alcohol. Alkalizing fruits and veggies are better choices. No soda or coffee. Eat smaller meals throughout the day instead of large ones. Don't smoke! Avoid pressure under your stomach: loosen belts and watch weight gain. There is some thought that peppermint helps. For me, it's worse.
When I do get acid, Instead of proton-pump inhbitors like Prilosec, I'll chew a few Tums or drink a small amount of Bicarbonate of Soda (baking soda) diluted in lukewarm water. Another natural and less salty alternative is a regimine of oral activated charcoal.
