Fruits vinegar for drinking

I bought two kinds of fruits vinegar, grapefruit and mango, for drinking. The fruits vinegar is less sour than general vinegar to drink easier.
Because I like alcohol very much, I drink alcohol like beer, wine, Sake and wisky every night. However, for my health, I drink fruits vinegar instead of alcohol to give my liver a rest at least twice a week.
Japanese people knows vinegar is very good for their health and there are many kinds of vinegar for drinking in Japan. We mix vinegar with wather, soda or milk to drink easier.
One bottle of the fruits vinegar is about 1500 yen. It is more expensive than general ones, but more cheaper than liquor.
