Strangulation with zip ties?

[Mocha]

In the woods with two fourteen inch zip ties, I'm thinking just tightening them around my upper neck (above adams apple) and waiting to pass out should work, but I'm scared. What's the consensus on this? How long from ligature strangulation until I lose consciousness and how long after that until I'm dead? I know is I want to be gone today, but I also know I'm scared.. I want to minimize the latency between attempt and death but I don't have a gun.

I think a ratcheting type device would work better, if you're inclined to go this route.
