What is the LD50 for acetaminophen?

I hear its around 800 milligrams per kilogram of body weight, I weigh 64 kg so its around 51200 g of acetaminophen to kill me, but small doses over a large period of time can cause severe liver damage.

The Tylenol bottles always say "It is hazardus to exceed 4,000mg (4 grams) unless advidesd by a doctor. So if you take say, 10,000mg (10 grams) you would probably have sever liver damage, or even worse, liver failure.
