Oh my gosh, me too!
I've been all over the place... I was a major night owl when I was a young kid, then for some crazy reason, I kept waking up around 5:30 every morning for a while, then I kept going back and forth between going to bed at really random times and getting up early and getting up later the next morning. Really crazy internal clock, lol. But now, I'm back to my beloved habit of being a major night owl!
