OMG! DON'T DO THIS!! ANTIFREEZE consumption is a horrible, horrible death. Let me find an article that describes the effects for you. Brb ...

I wanna know what he did to keep from calling for help. Wonder if he took something to knock himself out right before he drank the antifreeze because I cannot imagine ANYONE not succumbing to the pain and calling for help once the symptoms really kicked in.
Antifreeze is a liquid used to cool engines. It is also called engine coolant. This article discusses poisoning caused by swallowing antifreeze.
