Saw a link to dsps in a (the?) Wiki. Seems that my condition is documented or at least the signs match. I just simply don't fall asleep before around 04:00, except if I try to nap during the day. That makes a gap in something like 18:00 - 04:00 with little hope of going to sleep. It's weird and plays merry hell with trying to keep in sync with the world (world like SO, public transport, lectures etc). *sigh*

Hm. I guess the doctor for the army did more than a good move in releasing me from peacetime service hearing I'm an insomniac of some sort. (It probably wasn't about the psychological tests. *cough*)
