I started out taking my doses once per day becuase I had scar tissue that burned like heck in my throat. Internal jaw surgery in case your wondering. I now take 7 drops twice per day. I started with 1 drop in 8 oz. (mix) and then went to 2, 3, 4, over a month. Then went to 5 in 16oz and now 7 drops in 16oz mix twice per day.
My mix-8oz water, 8oz apple cider, 1 tsp. ACV, drops of iodine. This keeps my throat from stinging but very few people have the same problem. I am gearing up for a liver cleanse so the apple cider is for that purpose.
