Trouble sleeping , insomnia -_-

Elise • Hi my name is Elise and I'm 27, my husband and I got married in May and are expecting our 1st baby together. I have a 4yr old daughter from a past relationship . We are stationed in Hawaii :)
So I'm 18 weeks today and the past few nights I have tossed and turned and been unable.to get a good night's sleep . Is anyone in the same boat ?
