Just letting go

"And do you know what it's like to go for days on end without sleep, for weeks with only two or three hours out of the twenty-four? Do you know the sensation, Admiral Starr? That fine-drawn feeling with every nerve in your body and cell in your brain stretched taut to breaking point, pushing you over the screaming edge of madness. Do you know it, Admiral Starr? It's the most exquisite agony in the world, and you'd sell your friends, your family, your hopes of immortality for the blessed privilege of closing your eyes and just letting go."

- Alistair Maclean, HMS Ulysses.
