No sleep and frustrated

Brittany • Mommy to one sweet girl, expecting another precious girl in September
I'm on a full week of zero nights without complete rest. I toss and turn all night. And I'm anemic so my energy is already low during the day... being tired on top of that is not fun at all! My doctor has recommended Benadryl or Tylenol PM as sleep aids, but I don't want to take a pain medication at night when I'm not in pain. Does anyone else have any remedies that have helped during pregnancy?
