Most of the problems I encountered is the acidity content of the ACV (when taking long term) may lead to some swelling. Therefore, in event of a real problem, the common remedy is to either take baking soda solo, which is 1/4 teaspoon of baking soda twice a day since the body practically used up available bicarbonates as it is. For the other people, who don't have problems, ACV and baking soda can be used as 2 tablespoon of ACV plus 1/4 teaspoon of baking soda in 1/2 glass of water, since the pH is relatively neutral at about 7.0, initially anyway.
If I have problems with ACV use, I will likely take the baking soda alone. The baking soda should help with the swelling and acid reflux better. If not maybe 1/16 teaspoon of milk of magnesia (to kill of the bugs in 1/2 glass of water), but I think those are generally not necessary except for ulcerative colitis.
