Or your liver. 90mg's of vicodin would add up to a ton of Tylenol. Even if they're Norco's, that'd 10mg hydro with 325mg of Tylenol per pill which = 2,925mg of Tylenol. I think 3,000mg/day is the recommended maximum dose. I can't remember if Percocets have Tylenol or Aspirin mixed into them. If it's Tylenol, you are way over your limit for the day. If your pee is brown and your poop is pale gray tomorrow, you might be fucked.
