I just want to share my experience but you'll probably have better luck than me. All I had was a scarf or sheets on hand, and a strong shower door the one with sliding glass doors, I tied it to the metal bar. I had that hanging up there for 8 months. I tried and tried, almost daily. I had to put a thick blanket on the ground because it was uncomfortable. All I could do was compress my jugular, no matter what I did I couldn't get my carotid arteries. My face and eyes would bulge out of my face felt like I was exploding and no sign of passing out. I'm not sure but I was 100 lbs anorexic at the time, so maybe that had something to do with it. I've since gained almost 60 lbs so I'm not sure if it it'll work if I tried again.
