Combat fatigue at work?

Michelle

I'm 5w6d and have noticed the fatigue already - I get home from work at night at 6:15. By 8pm I'm dead on the couch and my husband has to wake me to go to bed.

Today at work, I'm trying to concentrate but literally feel like I'm about to start snoring. What do you guys do to help fatigue during the day?? The only thing I can think about is my bed right now.
