lol, he's talking about the APAP dose of 4000 mg per day, not hydro! Could you possibly imagine 4 GRAMS of hydrocodone per day?

Anyway, that shouldn't be causing diarrhea, so it's worth checking out with a doc- maybe you've got some kinda infection or other bowel problem that needs to be checked out? You're not taking nearly enough APAP for that to happen.
