How? I thought you weren't supposed to
okay let me tell you second by second.
0 to 1 - Not much. Just very little dizziness.
1 to 2 - The chest feels cold. Dizziness increases. Vision starts to go black.
2 to 3 - Vision is now almost completely black and the sense of hearing is lost. I feel tingly in my head by this time. tingly like needles. It isn't painful but very uncomfortable.
3 to 4 - Vision is now completely black. Dizziness is extreme. can't think properly. But can still count the seconds. And now legs and hands begin to shake.
4 to 5 - Legs, hands and the head shake severely and consciousness is about to go completely.
then I can't continue because my legs give in, I go down with a wham and the ligature hurts the neck. So in my case legs give in just a second before I go lights out completely.
