I understand your pain of not getting partial to work. 5 attempts to far and never lost consciousness.
My partial attempt two days ago, resulted in me spitting up a little bit of blood afterwards. No damage to the outside of my neck, much less pain compared to my previous attempts. I have no idea how I didn't restrict my blood flow enough to pass out, despite probably bleeding on the inside of my throat. Feeling kinda desperate, afraid I'll jump in front of a train or something, which I know is bad because it involves other people.
Partial is hard, for me at least, still trying it though.
