Many years ago I watched something akin to this occur. Some guy I did not know (I was in the Army at the time) apparently made a wager that he could down a 1/2 pint bottle of everclear in one go and did. Won the bet but spent weeks in the hospital afterward. I'm told it was touch and go for awhile whether or not he would survive.
I found several teenagers a few years ago getting drunk on the state land near me as one of them was proceeding to die in the ditch.
I was taking a late night ride on the backroads and saw some legs sticking out of the ditch. It was a kid about 17, unresponsive, barely breathing with a slow weak pulse, laying with his head downhill. His friends started staggering out of the woods to see what was going on and telling me he was OK.
I made them get him sitting semi upright so he wouldn't choke if he started to throw up and sure enough he immediately started to throw up while he was passed out so I made them lean him forward to make sure nothing remained in his mouth. I called the ambulance and the friends all fled.
The paramedic said it looked like basic alcohol poisoning to him and they hauled him off to the hospital.
