After 3 weeks of continual use (2 tbsp. diluted in half a cup of water with every meal), I have almost completely cured my acid reflux, chron's, ibs, hiatal hernia, and closed illeocecal valve. Persistence, and consistence is KEY!!
I find that a tablespoon of ACV with water before a meal significantly reduces the swallowing discomfort due to Hiatal Hernia. It is not a cure, but it definitely makes swallowing easier for me.
