Wiped Out

Sorry I'm late posting today's post.  Don't know if it's the oncoming winter, the weather turning colder, that it's now holiday season, my circadian rhythm out of whack because I had to work for my parents.  But for the last two days, ever since I picked up my parents from the airport, I've passed out around midnight or 1, way before I usually do, and woken up around 9 or 10, way too early.  I've also felt very sluggish when awake.  Is this a start of a shift to new conscious hours -- namely, hours that are alike everybody else's?  I shudder to think.
