Dreg

to the last dreg

What makes this pretty abruption? What too curious dreg espies my sweet lady in the fountain of our love?

O! be the cup of joy to thee consign'd, / Of joy unmix'd, without a dreg behind!

Fear and trauma may drain to the last dreg the dischargeable nervous energy, and, therefore, the greatest possible exhaustion may be produced by fear and trauma.

“Ay, thou doubter! Ay thou disbelieving dreg!”
