Defecation immediately upon waking.

If one habitually suffers morning duece symptoms (being woken by abdomenal pains, excessive farting and/or swamp ass) diagnosis of Morning Deuce Syndrome (MDS) is likely.
"I couldn't sleep in this morning.. a god damn morning deuce woke me from my slumber."

"Yeah, so I ran some tests and well, you came up positive. It looks like you've got Morning Deuce Syndrome and well, here's the real kicker... you may never sleep in again."
