Postprandial

postprandial \post-PRAN-dee-uhl\, adjective:
Happening or done after a meal.

When I wake up in the morning, I can have my usual breakfast -- a slightly bizarre concoction of three kinds of cold cereal topped with grapes and a cup of decaf -- and then stagger back to bed for a postprandial snooze.
-- Sylvan Fox, "It's Less Hectic Staying Put In One Place", Newsday, April 3, 1994
