That's also exactly how some poisonous mushrooms kill you, which I mentioned earlier. You become seriously ill for a bit and you recover, but your liver is already destroyed and you die a few days later. The only way to save you is for someone to think to test for that and to get you a transplant before then, so practically impossible.
