Ah yes, know all about that!!! I am at the other end of my preg, and awake for different reasons, but I too am awake a lot of the night most nights.
Early on I'd be awake a lot, but it did settle for me then started again in the 3rd tri due to needing to pee so much, can't get comfy, can't breathe properly etc etc.
I really hope it gets better for you really soon and you're able to get in some afternoon naps until then.
Take care and congrats on your preg!!
