I found it extremely difficult and very traumatic and it has put me off trying this method again. I did a lot of research, used a necktie with a slip knot as recommended in the hanging megathread. I put it through a door hinge. I just dangled and strangled and choked and boked. It went on for endless minutes and I didn't come close to passing out, just made a mess throwing up and gargling on my own vomit and secretions. The tie then ripped in half and I landed on my ass on the floor.
Compared to my attempt with fentanyl OD, when I underestimated my tolerance and just got high as a kite and spent a blissful afternoon, hanging is definitely not for me.
