My friend.
He passed out around 40 seconds in.
Sadly he was found couple minutes later and interrupted.
Had a coma for a few days. Then couldn't walk for a few weeks. Extremely lucky he did not become a vegetable.
He is still attempting today, just being EXTREMELY careful and MAKING SURE NO ONE is there for a good few hours to interrupt.
He described the coma and the hanging as "nothingness, but better than life"
