Anyone else have insomnia?!!

Oh my goodness...I've never had issues with insomnia in my other pregnancies but this is just getting ridiculous. I get maybe 4hrs of sleep total, but broken up sleep because any little thing wakes me up. Once I'm awake it takes me another 2 hrs to get back to sleep, and then all my kids are up by 6am. I'm exhausted!!!! Anyone else in the same boat!! I'm 21w3d
