>yeah, please drink half a litre, or even better 2 litre of vinegar and report back to us how that went.

And what is that supposed to prove?

People regularly drink "half a litre" or 2lt of Coke and report back just fine.

The main reason not to drink half a littre of vinegar is its taste and extra acidity.

If it had the same acidity as Coke AND better taste it would be fine to drink.
