Actually, acetaminophen isn't an NSAID : P
http://en.wikipedia.org/wiki/Acetaminophen
If it was an NSAID it would cause stomach issues as opposed to liver hepato-toxicity.
And you don't face acute liver toxicity until you hit 10-20gs (10,000-20,000mgs) in a 24-hour period. What you are speaking of is long-term chronic use. It will cause damage over time, but so will everything else you do.
It can be classified as an NSAID by some, and not by others
It is currently in question on what it "officially" is
