Past about 24 hours for me I start seeing things out of the corner of my eyes. Somewhat before that (on night's I get maybe 3 hours sleep) by the end of the day I get easily startled.
I've got no clue how people stay awake for more than 48h; just last week I fell asleep in front of the computer after being awake for 24h. For me, it requires mental gymnastics to be able to go beyond that.
