I'm a "seasonal" coffee drinker.
In the colder months, I'll drink a whole pot before 10am.
When it warms up (spring/early summer) I might have two or three cups.
In the summertime, when it's hotter than the south side of hell, I might have one or two cups early in the morning.
Rarely will I ever drink a cup after 11am, but if we have company, I'll usually put on a pot and have a cup or two.
And for the record, Dunkin' Donuts is the only brand I use.
