There's really not much information (on this website) about a method like that, but like everybody is saying, I imagine it'll be pretty unreliable, and very painful. I understand how desperate you must be feeling to suggest something like that, but the last thing you want is to be in even more pain. I hope that, if you look through the resources section, you might be able to find a better method. Good luck with everything! https://sanctioned-suicide.net/threads/suicide-resource-compilation.3/
