Have you experienced Shallow Water Blackout? Explain What was it like?

Answer 1

no

Answer 2

Most Shallow Water Blackout victims do not survive. Victims of SWBO never experience a gasp reflex or feel the need to breathe. They simply pass out pass out beneath the surface and are more often than found in the same dive position they started in only by that time they've experienced such a lack of oxygen that they are not able to be revived.

I've never experienced it myself but it is supposedly a very sudden, painless death.
