Sleep Deprivation stages

I have been up since Wednesday at noon (Approximately 86 hours) and I plan on staying up until 7 am tomorrow for a breathalyzer I have to take for probation, (that will be in 5 hours) and then take a bunch of sleeping pills and sleep for a day or so.

But my question is, are there any documented studies on the stages? Like x hours without sleep = this symptom, xx hours without sleep = this symptom, etc.

From my past experience, I usually begin to auditorily hallucinate at around 30 hours, when 42 comes around very minor visual hallucinations and when you hit around 56 you're mind state is just completely fucked and weird.

The longest I've stayed up previous to this is 77 hours, so this is my new record. Yet I'm not having any exceptional visual hallucinations. The main two things that are getting to me is whenever I heard a song on the radio that is turned at a lower volume, it ALWAYS think its the song Eulogy, by Tool. It's really starting to trip me the fuck out.

Second, I can't talk for shit. I've got like a speed-deprivation-induced-speech-impediment.

Anyway, any documented researches? What're your records?
