So I never had the issue with my son where I was so uncomfortable I couldn't sleep. If I had troubles while pregnant with him I used unisom and passed out. This time around I don't know what it is. I work night shift but did while I was pregnant with my son. I come home eat and get ready for bed. I lay in bed for hours upon hours to try and fall asleep and I can't. Super restless. I keep my husband up because of it. Unisom don't work this time. And I do everything I can possibly think of to try and help me sleep. Any help?

I have a body pillow, I use the boppy to "lay" on my stomach. And keep light blankets on me. When I go-to bed I am already exhausted just can't sleep.
