Anyone else just EXHAUSTED?

I'm almost 9 weeks pregnant with my 2nd baby and all I want to do is sleep!! But then night time comes and I can't sleep because I can't get comfortable (I am a stomach sleeper and can't really do that now). I take a nap any chance I get, whether it's 1:00 in the afternoon or 6:45 at night! Anyone else feeling this? How are you dealing?
