1s Trimester Fatigue

Is there anything I can do to combat 1st Tri fatigue? It hit me like a ton of bricks this week and I am just feeling constantly exhausted. I remember it being bad when I was pregnant with my twins, but I wasn’t caring for 2 toddlers and had much more time to rest. Even on a full night of sleep, I’m waking up feeling as if I got hit by a truck and I’m only 5.5 weeks 😩😩😩. One of my twins woke up at 3 am last night for about an hour and I literally cannot stop yawning at my desk today. 😴 Seriously considering taking a nap in my car at lunch time.
