I took Prilosec for years for acid reflux. Every time I tried to stop, the reflux would come back in the night. My doctor said to just keep taking the Prilosec. Internet research led me to the dark ACV liquid, which I started taking six months ago, and stopped the Prilosec. I have had no acid reflux in those six months. About three months ago, I changed to Botanic Choice capsules, which seem to work as well as the liquid, and are much more convenient. My wife & daughter now also take them for general wellbeing, and for a claimed side-effect (in the research) of weight control. Of course, the manufacturers can make no such claims.
