I'm not saying it doesn't happen, want it to happen to you run an IV of pure water into your arm. I have no idea why the argument turned to overhydration, but I remember someone saying LSD and weed are 100% safe, because no one ever died of an overdose, therefore that makes it safer than water. I just tried to explain it hard to get to that point your body will try to stop it from happening, and LSD is not safe, that was my point.
