How do I avoid brain damage with partial suspension?

[Gerard de Nerval]

Why did you fail?

Ligature wasn't tight enough in a really rough rope. I should have used a different rope or lubricated it. While I was convulsing I think I heightened myself against the closet wall which caused blood to flow back to my head.

Alright, so apparently this is true for some methods/accounts of a person losing consciousness. I honestly had no idea that it actually varies from instance to instance. I'm extremely interested in this now and will have to look into this more. Sorry for the inaccurate post earlier. I came across a post by Ben that said with hanging it could be up to 15 minutes before irresversible damage occurs to the brain. Very very interesting! Had to come back and correct once I found out. For some reason unable to just edit my previous post. Hope this helps dear!
