I’ve been eating APAP containing pills by the truckload for over 20 years and I’d suggest not taking 5500mg of naproxen at once. Will it kill you? Probably not. Will it cause renal failure doing it one time? Also probably not, but taking even one naproxen makes my stomach hurt like a motherfucker. Not sure what it is about them but they mess my insides up pretty good every time I’ve tried to take them. AFAIK they’re known for being really rough on you, not so much health wise but for causing more pain than what they give out in relief lol. IMO 300mg Codiene isn’t worth that stomach ache.
