Insomnia??

I'm 8 weeks today and basically since I found out I was pregnant, I've been waking up in the middle of the night WIDE AWAKE anywhere between 2-3.5 hours before I need to get up. I can't fall back asleep for hours and then when I finally do, my alarm goes off 15 minutes later. Is anyone else dealing with this? It's torture to just lay here as still as possible so I don't wake my husband and try to turn off my thoughts. HELP :( I'm exhausted but can't sleep.
