I just took 3500mg of acetaminophen (apap) at once, am I gonna be okay?

You'll be absolutely fine. You'll probably pee extreme yellow for a week or so but you'll physically be ok.

Within first 24 hours of overdose......nausea,vomiting,diarrhea,appetite loss,sweating,irritability. In the next 24 to 72 hours.....liver damage causing upper right abdominal pain,yellow eyes and skin,dark urine,confusion,low blood sugar,bleeding.

You need to call your local poison control NOW! You can seriously damage your liver -- to the point of irreversible damage. You may feel fine now, but the symptoms of overdose can take up to 24 hours to come on.

maybe you want to call poison control, just in case. becuase it all depends on your age, weight, etc.

just to be sure.

they may want you to throw up or go to the hospital for the chalk thing.

You'll probably get pretty sick. Stay near a garbage can or the toilet.

make yourself throw up before they all dissolve
