Or, like frosty said above, could make you accidentally poison yourself.

this won't surely become a recreational, available over-the-counter drug for a Friday night out. I can't see it legally used other ways than within a structured rehabilitation program with medical support.

This kind of stuff is deadly "as is". The effect caused by abusive alcohol intake is a way your body is trying to keep you away from it! Disable those mechanisms are you are good for an eternal underground tour in box.

I completely, used properly this could help a lot of people. I'll hold my breath and see how it works in reality, because there are some issues they don't mention. For instance, reducing the effect of alcohol don't in effect reduce the craving. So this could be helpful, like you mention, as a part of a therapy.

A lot of people are like that actually. No one wants to be that one guy in the party...

It doesn't fight the alcohol itself. It blocks the receptors that react to alcohol, so your blood stream could be all alcohol for all I care and your body still won't detect it. Your liver won't thank you though.
