The "standard dosage unit" in Canada is 325 mg (for adults), with extra-strength pills containing 500 or 650 mg.
1000 mg is pushing the daily limit (4000 mg, but it's got a halflife of ~6 hrs, so...)

Like many people, when I have a headache or a sore muscle I take the dose recommended on the Tylenol bottle: 1,000 milligrams. It is not even remotely dangerous.
Furthermore, if the original commenter is using acetaminophen to reduce rare psychological pain the margin of safety is even larger because she's using it only rarely.
A one-off 1000mg is, as you say, fine but if you're maintaining at that level, you are literally right at the DNE limit.

500 mg (in each caplet)
