Hell-served-for-breakfast

This expression was used in 'The Quitter' by R.W. Service.
Would you help me with the meaning of it? Here is the first
stanza of this verse:

When you're lost in the Wild, and you're scared as a child,
And Death looks you bang in the eye,
And you're sore as a boil, it's according to Hoyle
To cock your revolver and ... die.
But the Code of a Man says: ``Fight all you can,''
And self-dissolution is barred.
In hunger and woe, oh, it's easy to blow ...
It's the hell-served-for-breakfast that's hard.

Thanks in advance
