Aww I feel for you,dr calls it pregnancy induced insomnia (at least in my case) and boy does it suck! I have no problems falling asleep however staying asleep is another matter!
Here are drs and other peoples suggestions to me try them unfortuantly none worked for me so I have to nap like a cat all day or I'll be even more zombie like..... I hope some/any/ all work for you
1. Switch tv off an hr before Bed and read, go to sleep when you can't read any more
2. Hot milky drink an hr before bed
3. No naps during the day
4. Eat something before going bed as your metabolism doesn't switch off when your sleeping
5. A walk in the afternoon evening
6. Classical music played at a low volume
7. Lavender spray on pillow - (I asked my dr if lavender is ok in pregnancy and she said yes- providing your not consuming it!)
8. Warm bubble bath
10. Dairy to write down all days stresses/ worries/ anxiety
11. if you spend 20 minutes trying to sleep but can't get up and do something else then try again in half an hr or so
