Stomach pain with Kombucha Tea

I had been drinking Kombucha tea for a few weeks about 4 ounces a day and than started developing incredible stomach pain in the pit of my stomach that would not go away and it developed hours after drinking it. When I stop drinking the Kombucha the stomach pain goes away. Is this too much acid?? Is it related to gall bladder or detox?? I just can't seem to drink it without this happening. Anyone else have this experience?? Thanks. Tweet
