This is a
shameful attempt at advertising.
Until someone tells me otherwise (please do) I am an advocate of tourniquet over hanging. I'd even say it can be in the top 3 for everyone. My experience linked here. I'd link others but until someone gives the link, I don't have any anecdotes to provide so until then I can only offer mine.
I feel like the tourniquet method should be stickied in those 'resources' posts or something of the like. As my post indicates, it seems VERY effective initially. After some digging from the various 'resources' posts, I was able to find 1 site the provided pictures of people who died via tourniquet method (if I remember, I'll search and link). I'll have to check again to see if it's mentioned but it does not appear anything special was needed nor was there need for any complicated preparation/setup.
You can buy your CTB for
<$25 (if the linked is no longer available, the other options after shipping/tax are about $20) if you're lazy like me.
If you take the precaution I detailed (handcuffs), I cannot conceive of any way this fails. Obviously the chances of it failing are sizable if you're doing this in your room/hotel room so it's up to the person find a place that is reasonably secluded.
