How much wine is too much in a night?

I'd be interested in other opinions on the vacuvin. Good science would suggest that someone open two bottles of one wine, plug one and vacuvin the other. Or maybe refrigerate yet another one.

I've thought my vacuvin aided preservation, but a plugged bottle may work about as well.

At any rate, this seems to be an interesting research topic. Perhaps let Consumer Reports compare the different systems.
