Interesting question.. but I believe that attempting to hurt yourself badly enough to cause death is unlikely to result in no side effects if you fail.

N is fail proof you either die or survive without any permanent damage

I am not sure this, but SN looks like fairly clean about side effects, and maybe partial as well, and CO.
Any method using drugs, barbiturates, benzos, I would not knew what to say about.
Jumping and household methods, could be worse about side effects i think so.

Everything comes with risk. Especially if you have a known or unknown physical condition such as heart disease or some other organ dysfunction that whatever you take or do could amplify

Partial hanging if failed could leave you with brain damage.
