Anyone else exhausted to the point it’s debilitating early pregnancy ?

I’m 7 weeks. And I am so tired all the time. I sleep through the night and wakeup feeling as if I didn’t sleep at all. And then I usually take like a 2-4hr nap in the afternoon because I can’t stay awake.... it’s making me sad I can’t get anything done and I can’t feel refreshed and awake 😩 I also can’t drink coffee because the smell of it makes me gag.. how convenient.

Anyone else ? Is this normal...? What has helped you?
