I have been doing 2TBLs of ACV with 1/4tsp of baking soda in water 1-2 times a day for the past week, while taking my 20mg of omeprazale (ppi). My symptom of GERD is a burning sore throat. After a week I stopped the meds and took the "formula" first thing in the morning on an empty stomach, and then brewed my normal 2 mugs of 'low-acid' coffee (which i buy on-line). About an hour later, I had a whey protein shake, and about an hour later, I had horrible watery diarrhea!! This continued throughout the day; all I ate was chicken. WHY?? I was doing so good with the ACV and baking soda, why would stopping my meds cause this? I stupidly drank it again before bed last night, and had the same watery diarrhea this morning...I also took my ppi because I was afraid of symptoms coming back. Anyone else have diarrhea caused by ACV/baking soda? Love this website!
