How do you ladies manage the lack of sleep, and just overwhelming fatigue??? 
I cannot nap, because I'm just not a naper, and I just can't sleep during daylight hours. So the "sleep while the baby sleeps" just doesn't work for me. 
Is there like a pill? Or some tea? Or just idk- some type of energizer to drink? I am so sleepy sometimes , it physically hurts to keep my eyes open.
