I wake up when it gets light out, without exception. This has been happening for weeks now. Even if I was up late drinking the night before. This is awful.
One of the reasons I'm excited about my upcoming move is my new bedroom will be easier to block sunlight in during the morning.
@dgonyeo warning: may not be the early sunlight alone. This phenomenon comes with age as well.

@awpsys this is due to my room in Berlin having a large window next to my bed and no curtain, so I got trained on waking up to the light.

I'm assuming the age induced version of this lets you sleep past 6:45 am if you go to bed really drunk at 2 am, whereas my current affliction does not.
