Never go to bed a loser.

[pinkie9]

Never go to bed a loser. Always get up a winner.

Isn't 'as' necessary in these sentences?
(Never go to bed as a loser. Always get up as a winner.)
Is it wrong if I add 'as'?

[SoothingDave]

Not necessary. Not wrong to add.

Thank you!

Is the rule same in this case too? ("As" is not necessary, but it's not wrong to add it.)

You will come through (as) a winner.

If someone knows a grammar book or a website which explains this (about the necessity of "as" for a verb + these types of noun), please tell me.
