The perfect way to go for me would be while trekking out in the woods or in the mountain.
I would setup camp with my tent in a remote place, far from any people or prying eyes.
While watching the sun go up, I would rest my back against a warm rock, feeling the rising heat from sunrays tickling my cheek.
When the time was right I would drink my N, chasing it down with a shot of vodka.
Sitting there I would draw my last breath. Realizing dying isn't that bad.
