Well that didn't exactly go according to plan.
I pulled an all nighter, spent most of yesterday walking around like a zombie from lack of sleep. By 20:30 I was too tired to keep watching a movie and decided to call it a night and sleep, with my alarm set for 9am. I thought it would get me back on a decent time scale for sleep. I woke up with my alarm, turned it off and instantly fell back to sleep, not waking up again until 11:30.
At least I'm waking on the right side of 12, but only just.
