As a kid & young adult it seemed like it would take forever to finally fall asleep; don't think I ever spent less than an hour head down on the pillow wondering when the hell I was gonna finally konk out. Fortunately, once I actually was asleep, nothing could wake me before the alarm went off.

In the last 3 or 4 years I've noticed a definite shift in my sleep habits: I definitely fall asleep much quicker these days, but I also wake up to pee every single morning sometime between 4:00 and 5:00AM, regardless of what time I got into bed.

I suppose it's also worth noting that from the time I was ~19 until probably age 40 I almost never got into bed before midnight...whereas now it's extremely rare for me to not be in bed by 11:00 or 11:30.
