Sleep inertia is a wonderful phrase, one I'm sure to add to my personal lexicon. "We found the cognitive skills of [some] test subjects were worse upon awakening than after extended sleep deprivation," researcher Kenneth Wright said. That's because in some of us, the cortical areas responsible for problem-solving take longer to wake up than other parts of the brain—as much as 12 hours, in my case.

On the sleep credit card, I only seem to be able to cover the minimum payment each month.Some days, my most frequent waking thought is about when I will next be able to sleep!
