I just want to sleep!

So here I sit at nearly five in the morning wondering why in the hell I can't sleep! I had insomnia in the beginning of my pregnancy but have not had it for a few months. We finally got the girls sleeping through the night again after moving them downstairs into the same room (not a fun experiance) and now I can't sleep. I have been awake since two-thirty and after tossing and turning for an hour and a half listening to Ryan snore, I decided that I would try and do some homework because during the day when I do it, I can't stay awake so it should do the trick right? WRONG! Still wide awake, even drank some Pero hoping the warmth would help make me sleepy. I know that in about an hour, I will finally feel it coming on only to have to get up an hour later to start getting Addie and I ready for school. Oh well, what do you do? Good Times.
