Anticipation... of time zone changes?!?!?

Yeah, apparently. It started happening about three days ago... I'd begin getting really sleepy around 7:00pm and, even though I've worked really hard to stay up until my normal bedtime, I've been waking up earlier and earlier, anyway. Last night, I gave in to the sleepiness and headed to bed around 11:00pm, and woke up this morning at 5:30 (I'm normally a 1:00am-7:00am type of person). This is all just so incredibly weird... since usually? I need *light* in order to wake up, and it's PITCH BLACK here this time of day.

I finally decided last night that unless there's something I desperately need to stay up for, I may as well go to bed early... 8:00pm here is 4:00am in London, so it's not exactly like my body is trying to switch completely, but this could be a good transition method. And it's not because I'm sick or anything, I'm just getting sleepy early.

Still, it all seems very, VERY weird. I'm not used to seeing this time of day.
