Super tired all the time!

Dennyiel • Married to my high school sweetheart ;) we have four beautiful children a boy and girl, and a new set of boy/girl twins! Had a chemical pregnancy in September 2015.anovulation problems
So I'm 25 weeks with twins and no matter what I do I cannot beat this constant fatigue!!! I go to bed at a decent time and wake at a decent time during the week, and weekend's I allow myself a little sleep in time. 😀 But I still find myself dozing off in the middle of the day and still fatigued later. I do light exercise and meditation. But have cut out caffeine and coffee since I found out I was pregnant which was around 4 weeks. Any ideas how I can boost my energy levels? Or any twin Mama's having the same problem? I'm tired of feeling​like a zmombie! Yes I splet that right I do have other kids. Lol thanks
