I didn't complain, or go to doctors or even have any idea recreational or street drugs might alleviate some pain, but I was in terrible pain for a long time.  I took larger than recommended doses of paracetamol every day around the clock for months.  It didn't even help the pain.  Later I got liver symptoms, and I think it was due to this.

I'm sorry for your liver damage and I hope it gets better. However, what youbdidbwas pretty stupid. There is a reason there are doses that should not be surpassed. They don't put some arbitrary number on the back. There is a reason you're not supposed to take more than 4 grams of aceteminophen. Also I have no idea why you didn't check with your doctor first before deciding it was okay to take more than what it says is the limit. It's honestly no one's fault but your own.



   

I met Tylenol representatives later on.  They couldn't stop bragging how safe it is.

In doses below the limit, it is completely safe. Your liver is a filter organ, but can only handle so much at a time. If you push in more than can for, obviously damage will occur.

   

Also, I have read since then and looked into, and it seems the reason opiate prescriptions are mostly dangerous is all the paracetamol added to a great deal of them, as the ones without don't put the same strain on the liver.

Once again, opiates are completely safe (and derived from the poppy plant btw) if you follow the directions. However they can be addictive. But the opiates themselves don't damage any organs. They do slow down your cardiovascular system and can cause you to stop breathing, but that's not from any sort of damage. However most prescription opiates do contain an extra drug that is dangerous in high dosages. This is intentionally done more so to prevent abuse rather than drug effects. However if you follow the regiment as prescribed you don't have anything to worry about. Next time before self medicating, think. Don't let your stupidity end your life.
