That is not too bad, 1000 mgs/day should be tolerated fairly well by your liver, common medical advice recommends no more than 4000mg per 24hours and they say fatal toxicicity can start at the 10000mg/day level, but it all depends on YOUR liver, what conditions you may have, how much you drink, etc
If you need to be on narcotics for an extended period of time though, I personally would ask for an extended release opiate with no
acetaminophen.
