139 hours awake. (5 days, 19 hours)
That nearly killed me. I was okay after 20 hours. Around the 35-hour mark, fine co-ordination began to be difficult (writing, or picking up small objects was tricky). Near to 50 hours, I began to feel sluggish when I moved, and also began to black out for a few seconds at a time. At roughly 80 hours, the need to sleep was like a constant ache, and I couldn't really think. After that I felt less of a need to sleep, but the blackouts were more frequent, even if I was doing something (as opposed to just sitting). I also started to hallucinate - I was hearing and seeing things. At around 120 hours, I began to black out more frequently, but for shorter times - almost like tiny flickers where my brain seemed to switch off and back on again, and even thinking was difficult.
The strange thing was, even at that late stage, I was still partially functional - I was awake during a fire in my hometown, and over those days we managed to keep most of it under control, even with the intense disadvantages that came with the sleep deprivation.

29 hours asleep.
This time was unremarkable - I remember nothing, don't even remember a single dream. How boring.
