I am not joking. I have had a NDE. All your senses slow down, if you are listening to music, it speeds up. Then you go blank-a dreamless sleep, your ears go deaf.
That won't kill you, it will just fuck up your liver. Trust me, I had an extremely suicidal (and stupid) gay friend. He would continuously try to top himself with paracetamol and vodka, only to end up in A&E. The best way to suicide with paracetamol is with a staggered overdose.
