Weeks, years, decades later, sure.
PLEASE DO NOT. I have done this countless times, and it is the WORST FUCKING PAIN ALIVE! And you can't make it go away. I can't even describe it... imagine the most excruciating stomach pain and probably times it by 10.
I haven't done this in years, because I finally learned my lesson, after the doctors, and other professionals told me that they'd met people down the line, that died from liver failure when they took the OD years before. They told me because I'd done it so many times.. they probably thought I was a right idiot. It is true, it can take a long time, and they would NEVER give you a transplant, because you'd likely do it again.
I would never ever OD on paracetamol (again). Even thinking of it is bringing back memories, and I'm sitting here gagging. I'll never forget that... taste.. the pain. Not just pain, the agony. Sheer fucking agony. And I took a LOT, with other things (other times - sometimes just the paracetamol). Several times over the years, not for at least 10+ years now, and I haven't looked at paracetamol the same way.
Take it from me, you don't want this.
Please reconsider
