Exhausted. ALL the time!!!

I'm just at 8 weeks with my first.

I've had little to no morning sickness or other early pregnancy symptoms.

But my exhaustion is so bad! I go to bed early and sleep late. I have very vivid dreams and wake at least once a night. Then in the afternoons I have to have a 2-3 hour nap! I'm so so tired.

I've always struggled with energy levels because of other health things that zapped me. I used to drink one red bull a day (none now) to get through the day. (Actual coffee makes me even more sleepy.) Would take short naps only on rough days. My other health things are in check and fine for the pregnancy.

But will this pass or will I be doom to be sleepy at all times? Anything I do to help?
