For me it's not just "focus on task" but also tasks with multiple interacting components (sounds like programming?). Lack of sleep makes it very hard to follow interacting chains of cause and effect. I do find that for whatever reason the right amount of sleep deprivation makes me more upbeat and social (and silly). Like somehow the anxious, analytical part of me gets switched off first so the well-rested parts that rarely get used can steal the show.
