Bubble of no-sleep

The past few nights I've woken up in the middle of the night and had trouble getting back to sleep.
It seems to be slowly moving backward through the night.
Wednesday it was about 4AM, Thursday about 3AM, and now about 1AM.
No idea what causes it. Wish it would stop.

I'll grant you between getting ready to go to Europe for a week in 2 1/2 days, our anniversary party in 15 days, other job concerns I've still got and a bunch of other things, my mind has things to keep it busy.

I just wish it would work it out in dreams while I slept like it is supposed to do...
