Tired!!

At the beginning of the pregnancy I was extremely exhausted. That finally passed and I regained some of my energy. But now that I've almost hit the halfway mark, the exhaustion is back. I just don't feel like I can get enough rest at night. I honestly don't even know if I'm sleeping good at night. Some nights I know that I toss and turn (from not being able to get comfortable), but others I feel like I did. It's probably just because the babies are getting bigger and more active and they drain my energy. It's worth it. I love my babies and can't wait to meet them one day.
