My Disability: Sleep 2014 08 ~ 2016 12 Large

I have a sleep disorder, called a non-24 sleep/wake cycle.  It's a circadian rhythm disorder, and it doesn't respond to treatment.  This graph here was made by compiling 28 months of data in a convenient, easy to read format.  It has a few errors because of daylight savings time, but overall it's quite accurate.
Black lines indicate when I was asleep.
I dunno, I just find it fascinating to look at, though I feel to the rest of the world it is about as compelling as a new parent's chart for the circumference of their baby's cranium.  I have another chart for amount of time spent asleep, but I think one chart is more than enough for the deviantart community.
This also functions as an explanation for my sporadic availability.  Can't be online if I'm not awake.
