I was surprised too, but it did. I weigh about 90kg.
I felt very uncomfortable. There was pressure on my neck, but it just didn't feel like I might pass out any time soon. Maybe I would have if I had waited a bit longer. It was hard to breathe but I could still a little, so my throat wasn't closed completely.
I was also a bit drunk that night, so I can't remember all details any more. It's been some time since, too
