Honestly, unless they get to you before the acetaminophen is absorbed, you're fucked, there is no saving your ass. If you're really, really unfortunate (since they obviously wanted to die) you will end up with a liver transplant because you fried you liver. It's almost a guarantee that you being stupid has now caused someone else that legitimately needed that liver to die because now they won't get one in time. You will eventually wake up and find out you survived it, only to end up with a lifetime of anti-rejection medication that will leave you open to really nasty infections and cancer, with your lifespan ultimately shortened to a fraction of what it might have been otherwise. You better not try to kill yourself again because that would make you a double piece of shit. You will have taken a new liver that could have prevented someone else from dying, but you stole it from them only to have it go to waste, you heartless, worthless monster.
