i hope you read and are thinking of adding the cabbage juice and the pau de arco (very special herb) to your regimin, its so powerfull that you should notice a result imediately. Investigate why we get the regurgitation, and if you actually have gastritis, where the stomach lining and even more drastic the sphincter being damaged, comes from.
As long as you arent eating animal flesh, grains, greens or dairy and your system isnt highly comprimized by metals or other toxins the ut should only help but since you are still suffering find what will work along with that or besides or instead.
