The impact has been significant. Small servings of non-irritating food for months. I’m told the stomach lining does heal given time, and my symptoms are better now than a few months ago. The post I originally replied to sounded like a recommendation to take Aspirin speculatively as a preventative, which is exactly the mistake I made. Gastro resistant tablets might have helped, but the general advice is to be very careful with NSAIDs on the stomach (although I still use topical Ibuprofen gel when needed).
