As deadlines fly past, I feel compelled to stare at my monitor late into the night. This does two things:
Ensures nothing gets accomplished the next day either.
Takes away whatever health benefits a few hours of sleep might have brought.
Fighting off illness. Sore throat, runny nose, violent shivering, coughing fits, terrible headache. It feels like my asthma might be back. I'm nearly positive I'm feverish, but can't figure out how to read the thermometer to verify that. Anyway, those symptoms make sleep deprivation truly intense, and sleep itself intensely difficult.
