So sleepy, its scary.

So I am 8 weeks pregnant and I am so EXHAUSTED. Its so bad to the point its starting to scare me. I find myself falling asleep everywhere I go. Even while driving I'll either zone off and miss my turns or its even to the point where I am swerving on the road. No matter how much rest I get nothing helps. Anyone else have this problem. Work is becoming unbearable to stay awake.
