1,000 milligrams is not "pushing the daily limit". That is a normal adult dose and by a wide margin within what is considered safe for even chronic daily use.

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.
