I have been a loyal follower of ACV (Apple Cider Vinegar) for 15 years or so. It is remarkably effective. I won't be without it at home! Even my once doubting husband became a believer. It's the best natural remedy going. Take 2 tsp in a glass of water (i just pour 2 capfuls). If you can't hold anything down the best way to take it is by the spoonful. Just keep sipping a spoonful every 3-5 minutes, or as often as you can handle, and it will stay down. Very quickly it will take effect. Usually in 30-60 minutes it will stop the vomitting by killing the bacteria, which causes such sickness.
