first got GERD around Christmas, 2004. My wife had some Nexium around and I starting taking this. It seemed to work, but then the GERD came back. Tried Tums. Again, seemed to work. Changed diet (alkaline foods, removed coffee, some alcohol, etc.) Again, seemed to work. Since, I was a person who buys health foods, there was an item that I would eat on and off that was completely healing my GERD for awhile. Then I would run out and the GERD would return. That food was yogurt ! In fact it was goat yogurt (Redwood Farms). Any yogurt might not work. It must have beneficial bacteria (L. Acidopholus) and should be low in sugar. Just go to a health food store. It works immediately.
You can also take Acidopholus tablets (must be refrigerated!).
This Redwood Farms? Is it in the UK?
