I have that same problem. The vision goes blurry, body shakes, I feel like going all black and then I abort. Once you go unconscious, the entire body weight will pull on the rope and knowing that while going unconscious and having to face losing control of your limbs is too scary to go through. If you take a lot alcohol, you will begin to vomit. I don't have access to alcohol so I drank an entire bottle of sorbitol cyprohaptadine syrup. It made me extremely sleepy and dizzy after around 20minutes. Still, the survival instinct didn't let me do it. I have been experimenting with ligature strangulation for the last two/three days and have found that it works and it is easier to overcome the survival instinct in it(at least for me) as no body weight is involved. You have complete control of everything in it. If you are interested in it, then read the thread I posted yesterday on ligature strangulation.
