Insomnia, Anyone?

I am 4w1d and since I found out, I've been waking up earlier and earlier, regardless of when I go to bed. At first I attributed it to nerves and being eager to wake up and test. But the last two days I've been up at 4:30 am! I don't even work till 9! Has this happened to anyone else? 

How should I use my newfound freetime?
