Anyone else having trouble sleeping? I've been having issues even before I was pregnant. I take half a unisom to help with nausea and sleep at night, but there's just a lot of tossing and turning. It's also giving me some back pain. Our mattress is only 4 years old, and I have even tried a mattress topper and different pillows. I don't know if I'm stressed out or what, but I can't think of anything that would be causing this for that long! I forgot to mention it to my midwife, and don't see her again until October 10. Anyone have anything that helps you sleep at night?
