The trouble isn't so much waking up as it is falling asleep. If I try to go to bed at the same time every night, after a few of days I'll find myself staring at the ceiling for hours before I'm able to nod off. That leaves me with like four hours of sleep before the alarm goes off. That's simply not enough for me to be able to function at a reasonable level. So I end up turning off the alarm and collapsing back into bed for another hour or two. This pattern repeats and I end up in free-running sleep mode.
