I would not worry to much about that. At a certain point your brain will start to shut down certain areas. Leading to simple mistakes is a big clue. Once that starts happening I would not do anything that takes skill or much thought like driveing or working on a machine. I can not remember how long it takes but after a couple days your brain will pretty much force you into sleep. Sleeping is when you brain goes threw the days events and sorts them. It is also why it is better to study then sleep as you are more likely to recall what you read after sleeping.
