Water. Pure water (goog tap water is fine). At least 1 1/2 quarts extra a day with 1/4 teaspoon unrefined sea salt - mixed in a glass or liberally on food - (no table salt ever! Crystal cannot break down totally in system, causing many diseases). Without a doubt ibs and all gastric problems were cured in a few months after at least 5 years of problems. Whener you have acid stomach and like, dilute and do not add medications, unless there is something extreme going on. If you dilute the acid it stops burning logically and distention due to gas in the intestinal track is mostly the cause of pain, as well as inflamation. Further associated can be kidney problems - uric acid and stone formation - due to dehydration. If past middle age natural thirst gradually lessens and pain takes over to signal dehydration. According to researches, most medications can be entirely disgarded with simple water treatment on a consistent level. The drug cartels would be afraid of that one! Find a cool looking 1 pint water bottle and carry it around everywhere sipping through the day. You do not need to believe in it. Try the cure consistently and then continue to carry that little bottle around like your cell phone.
