What's the easiest way to commit suicide?

I don't want to hear any red herrings, give it to me straight I've heard it all. I live in Australia and i can't get an easy access to a gun. Ideally I'd like a pill that just puts me permanently to sleep. Is going to switzerland and using a death pod allowed or is that only for terminally ill?

I'm not sad or happy, i feel like an empty vessel. I'm as nihilist as it gets, i have no concept or desire for morality, relationships, sex, career prospects or hobbies.

Mods please don't delete this, i deserve to know this vital information, do not take away my agency over my life.
