anyone take long term Tylenol?

[Woodi]

ok, personal question: I've been taking 4, extra-strength Tylenol (500mg) per day since my heart surgery. It keeps the pain from the incisions (plus all the body-rearranging that was done) to a minimum. I also take one 12-hour naproxen (Aleve) at night.

The surgery was on Jan. 3rd. I'm beginning to wonder if I should taper off the Tylenol. Don't want to wreck my kidneys or liver.
