Buy Bragg’s brand ACV. To me, it tastes fantastic. Mix about a TBSP in 4-8 oz of room temp water and drink it. Do it 2-3 times a day until you get relief and then drink it every day.
I also recommend taking magnesium glycinate as it will dissolve stones.
I do the Bragg’s, too. 1 Tbs. in 8 oz. water. But I “sip” it with a straw, bypassing my teeth, as cider vinegar can be harmful to teeth over a period of time. And Bragg’s isn’t nasty tasting compared with the filtered stuff.
