What about liver failure caused by paracetamol? - liver failure condition_symptoms

I recently began to paracetamol tablets, "because I was sick, and now, when he saw, apparently it is very dangerous, and your liver will" die "or" no "E or W / OD if you call-ed .

Apparently, as little as 10grams can be fatal, but how long does it take to die is a "liver failure" (I guess that's what we die) without medical assistance. And how much hurt? How does it feel? Symptoms are evident?
