I'm a bit worried that I overdosed on paracetamol around 20 hours ago. I might have taken in over 4 grams. how long do symptoms take to appear? I've felt nothing at all, except for a bit of pain around where the liver is positioned, nothing major, just ticks of light pain occasionally. should I still be worried if nothing happened in 20 hours?
Hi there,
Could I suggest a trip to your local a&e hospital (or emergency room) and make it urgent. Paracetamol poisoning can take 3 or 4 DAYS to hit the liver, so as yet you are definitely NOT out of danger.
Please please go to the hospital and get medical attention.
I wish you good luck and a beautiful and happy future. 
PS let me know that you are ok when you have seen the docs
