I haven’t slept yet. And of course I’m barely phased by it.
If I don’t sleep tonight I’ll probably start hallucinating. After 48 hours that’s what happens with most people (including me).
Since I’ve always (literally) had Insomnia though, my Doctor would rather me be watched by Doctors and somehow fall into an induced state. When you’re awake over 60-70 hours, your brain cells start to die off slowly, and once they’re gone it’s likely to stay that way. He doesn’t want any Insomnia impairing my thoughts - even though it’s been torture for other things in life.
