I don't have access to many resources, so I'm trying to ctb in the most accessible way but I'm worried about it's efficiency.

I've decided to go with a purposely induced shallow water black out. (You basically force yourself to hyperventilate until passing out in a pool of water. Specifically for me it'll probably be a bathtub) But I'm not confident about my ability to pass out so I decided to use helium to help with that part.

I've discovered that a little bit of helium goes a long way for me when it comes to blacking out completely. Is this a silly method? I'm not entirely sure what else I could consider, but it seems like it would work decently.

This is probably the easiest way to do it. But only do so if you are really sure you want to ctb.

Also, don't inhale stuff too often as you can build up brain damage over time.

I could be wrong, but something you might want to think about, as you don't want to end up with the same problems you have now but compounded by horrible physical damage.

Maybe I'm just not understanding what you are proposing here.

You use helium to pass out, then how would you drown? You can't remove the helium when you are passed out - if you just inhale a few times, I don't think you are going to remain unconscious when the helium is removed.

Have you tried hyperventilating? Everyone who I have seen pass out from hyperventilating wakes up in just a few seconds.

The idea behind SWB is not that you hyperventilate and black out then drown. That's not what shallow water blackout is. You would hyperventilate, remain conscious, then hold your breath under water. The idea being that the hyperventilation does not trigger you to want to breathe while you are underwater, and then hopefully you pass out from holding your breath for too long.

At least, that's what free dive blacking out is and it's what the SWB method is based on, so it's a flawed method. Free divers do hyperventilate, and do black out, but it is a result of many different physiological effects - one of them being the decompression of the lungs as the diver moves from deeper water to shallower water, This combined with extremely long breath-holding is what makes them pass out.

I think the mega thread for SWB was closed because the entire idea is based on a faulty premise. You can't hyperventilate, pass out, and then just drown. You will wake up immediately and from what I've read on here from people who've drowned and lived, it is far from a painless or pleasant experience.

I do not understand this method, but good luck!

This seems horribly complicated
