Dear Kim: That would amount to about 4 tablespoons of apple cider vinegar, and 1/2 teaspoon of baking soda mixed in 1 full glass of water in one single dose. If taken at that dose and dilution, on an empty stomach should not cause a problem. If you want to take this, it is best taken during the late evening hours. In some rare case some people may get a mild diarrhea, but not likely since the pH is about 7 and it is diluted sufficiently.
