I think the key with bed time routines is being consistent. I had the light off by 11 pm on Friday. But on Saturday, my husband and I stayed up to watch a movie, and I didn't get in bed until probably close to midnight. Also, I tend to sleep in on the weekends (not naturally a morning person...) so that also throws off when I get tired at night. Last night, even though I shut the light off at 11, I was tossing and turning for at least an hour and a half (I've been stressing about my family and the holidays) before I finally fell asleep which made this morning really unpleasant...

I think I'm going to have to try harder to maintain bedtimes and not letting myself sleep too late on the weekends. Planning wake up and bed time by sleep cycle does seem to help me, as long as I can fall asleep when I want to...
