Late-onset Mondaymorningitis
I’d say Mondaymorningiasis would be better, but better yet would be to emulate the medical community and go straight to Latin:
Manedierilunaeiasis
All from the Latin (it’s a disease, remember!):
Mane: morning
dieri: of the day (dies, dieri)
lunae: of the moon (luna, lunae)
iasis: disease having characteristics of or produced by (something specified)
(Classical scholars feel free to excoriate me if I have the grammar wrong.)
In this instance, a disease having characteristics of or caused by Monday (Moon Day) Morning. Since it has the characteristics of Monday Morning, it will suffice for any day of the week, any morning after the night before.
I think the pronounciation should be something on the order of:
mah-nay-dee-air-ee-lu-nye-ah-sis
-itis: means disease or inflammation, but is usually reserved for inflammation, as in arthritis (joints), bronchitis (bronchial), bursitis (bursa—seen on Agora recently in the burse thread), and so on. Compare to psoriasis and elephantiasis, for example. Elucidating the etymology of these two words is left as an exercise to the student. 
My head hurts, my feet stink, and I don’t live Jesus.
That kind of morning, really was that kind of night.
Tryin’ to tell myself my condition is improving,
And if I don’t die by Thursday I’ll be roarin’ Friday night!"
—Jimmy Buffett
