We will be living in Germany for the next 2 1/2 years (military) we just took a 3 week vacation to the US and it's been a week since we got back and I can't seem to sleep. I sleep for about 4 hours then I'm wide awake then fall asleep a few hours later but then sleep till the afternoon. Yesterday I slept fine but today I again woke up after 4 hours. I know insomnia is a pregnancy thing but is that what this is? Or is this jet lag? I just want to sleep!!!
