Got some time to search my soul.

I slept through my alarm again today. At least, I woke up about an hour after my alarm would've gone off. It's a loud enough alarm to wake me up, and it's across the room from my bed to force me up to turn it off. I check it every night if I need to get up early in the morning.

It's entirely possible what's happening is I'm waking up just enough to turn off my alarm and then heading back to sleep without being aware of it. I really can't think of any alternatives.
