Doglover--I am the SAME WAY!!! As soon as I'm lying in bed, my mind starts going over things that happened that day, things I need to get done the next day, things that I need to do some time in the future, things that I shoulda/coulda/woulda done, etc. It drives me NUTS! My husband gets mad at me because he falls asleep as soon as his head hits the pillow, but for me, it doesn't always happen. And I'm not going to lie in bed staring at the ceiling for three hours waiting to fall asleep! I usually try to do something constructive with my time. Since I have three kids, keeping the house straightened up during the day isn't always possible, so I'll usually do some light housecleaning (nothing major or I'd never get to bed once I got into a large project). I also do 90% of my knitting in the wee hours of the night, but I have to try to do projects that don't require a lot of concentration!
I read at night sometimes too and that helps. If you're a praying person, sometimes it helps lull you to sleep while praying while you lie in bed (well, it does for me, anyway). I've also kept a notebook at bedside so I can write down those seemingly "urgent" thoughts I get that I need to do the next day that keep me up, and that helps too as my memory is getting really bad, and what could be worse than forgetting something that kept you up all night?
I'm a real cranky person if I don't get a lot of sleep. My husband can take "power naps" once in a while and feel great--me, if I don't get my 3 hour nap when I need it, I'm a bear! Maybe try some lukewarm no caffeine herbal tea (I shudder to say "hot tea" as we're in a heatwave here in the midwest right now!) or a nice cozy bath to help you get ready to sleep. I'm going to be headed that way soon myself (hopefully!)...I was having trouble getting to sleep, too, which is why I'm on KnittingHelp! :rofling:
