At least you had some fresh air in! My father, father in law and myself found out the hard way that its a bad idea to not have any fresh air in! We killed a bottle of Woodford Reserve whiskey chasing it with beers while in the garage for a few hours with the fryer going and as soon as we went in the house to eat within 10 minutes all three of us literally passed out near unconcious for an hour or two. None of us knew what the heck just happened so my dad looked into it the next day on the internet, mainly because he knew better than any of us passing out drinking so little lol, and it turns out that when you breathe in enough carbon monoxide it gets into your system and alcohol enters your blood stream over twice as fast hitting you hard and if you breathe enough of it and drink it will kill you . Coming out of it and breathing the fresh air in the house gives you a shock and it hits you really fast and you dont know what happened. He found all sorts of websites of people talking about the new rave of how to get trashed! I would never recommend that to anyone! New rules at my house are not an ounce of any form of alcohol near the fryer!
