36 drugless is pretty good.

A human body could probably do 36 days with the right go pills. With occasional micronaps.

Sleep deprivation is very interesting. Especially the insanity that results from it. There is no spiritual experience that parallels it.

Time dilation to the MAX. after the 4 day mark... Hours start to feel like days... and after 5-8 days... Days feel like weeks. You can think abstract concepts longer too...

Especially if you're wired on Methamphetamines and pushing two weeks.

Did your 36 hours lead to any Spiritual progression?
