[@vietmyke] Whatever you meant, rest assured that a couple bottles of whiskey could conceivably kill most human beings if consumed in a single night. Assuming they're 70cl at least. 

Then again, I'm hardly a toxicology student. It's the concentration of alcohol in your bloodstream that matters most in terms of immediate physiological consequences - the total volume over time is what will effect the liver. That's as much as I know.
