Hello, I wanted to give my own report (experience) to this:
So first of all, the key differences between Partial and Full are comfort, difficulty, and adjustability. There's no "best" option, as both achieve the same outcome. The ideal choice depends largely on your location and current circumstances.
Partial suspension: Following the OP's instructions, pressure must be applied to the carotid artery. To find it, place the center of your hand over your Adam's apple, then position your thumb and middle finger on either side of your neck. Carefully move your fingers until you feel a pulse.
Some people had trouble finding it, or they experienced negative effects. The important thing is applying the right amount of pressure. This pressure will differ depending on your body; some need more, others less. If the right amount of pressure is applied, you'll pass out within 5~10 seconds.
However, be warned: this action is irreversible. Before attempting this method, be absolutely certain of your decision. Once initiated correctly, even in partially suspended, your body will become completely immobile. You will experience an overwhelming sensation of weight.
Which rope?
It doesn't matter what you chose as long as it's: Smooth and robust.

Full suspension: The difficulty of this method varies greatly depending on your location and available options. It's essentially identical to Partial unless you decide to drop yourself from a certain distance. If you drop just right you'll black out instantaneously. You shouldn't do this unless you know what you're doing.
Success, Pain and Speed
This method boasts a near 100% success rate, assuming no major errors are made and any initial hesitation is overcome (which is perfectly normal). When performed correctly, the process is swift and causes maybe minimal discomfort in the beginning. There are many studies which you can find about this interesting topic.
