Method I've found that using compressions on my chest makes me black-out with partical.

I just got the closetest to CTB as i've ever gotten. While I was out earlier I noticed that my top undergarments were making me dizzy but still able to breathe so I had an idea to double up and use with partical hanging. Between the compression on my lungs and throat I blacked in a somewhat peaceful manner. I'm going to try this CTB method later as crazy as it sounds.
