Drowning, how heavy should weights be?

[_Minsk]

I want to stay chin deep in water, once I pass out from alcohol I want the weights to drag me down but im not sure how heavy they must be. Im between 65-75kg. Doubt anyone knows but just in case feel free to share, thank you

I think calculating diving weights would be an idea.

Calculator gave me 4lbs so roughly 1.8kg, thats less than I expected. Thanks

Maybe a cheap backpack with some rocks will do it

Weights should be at least the difference between your mass and the mass of the water your body displaces.

This makes me think of the application of weights in bridge jumping over water. It seems a small additional weight may increase success. *notes to self*
