Hey Lauren!
I'm sorry you didn't get any sleep again last night! I've been having the same problem the last four or five weeks now also. It always seems to be the worst on Sunday night - I think it's because I have to go back to work Monday. I found some info the net last week about insomnia and I copied it over to a post here. If you look under the "search messages" and type in "tips for sleeping" you should be able to find it. Another couple of things that have been helping me is chamomile tea at night. Being pregnant, you might want to call your doctor first - just to be safe. Two other things that have seemed to help me that I found on an insomnia support group online is to turn your clock around so you can't see what time it is throughout the night and to concentrate on the lights and patterns that you see when you close your eyes - when you start letting the thoughts in, concentrate on the patterns harder. I know the clock thing has really helped me though. When I can't get to sleep, I tend to look at the clock and think, ok, if I go to sleep now, I will have had 7 hours of sleep, and then a couple hours later of obsessing about not sleeping, I look at the clock and think, ok, 5 hours of sleep, and so on and so on and so on throughout the night until I'm all worked up in a frenzy. Turn that thing around! Surprisingly, it helps.
I don't think I got a whole lot of sleep last night either. I kept waking up throughout the night. I don't feel tired this morning and I do remember one dream, so I must've gotten some sleep. But, because I spent so much time tossing and turning, it doesn't feel like I did.
Another thing that has helped me get to sleep is to remind myself that it will be ok. You may be seriously tired the next day, but you're not going to die and you're not going insane. Also, being more tired, you will sleep better the next night.
Hang in there! I know it's frustrating and I know it makes you feel stupid and weak (that's how it makes me feel), but you will be ok!
