Help How long does it take to lose consciousness from full suspension hanging?

[-FrozenRobot-]

Going to CTB using Full suspension and I'm worried about how long it'd take to go unconcsious. Also, is there any way to overcome the SI?

Depends , if you have it on the main veins I forgot what they were called itll be about 8-20 seconds , if you jump from about 3 meter and break your neck it will take less than a second and if it goes really wrong it will be for about 3 minutes
