I've heard it's normal to get tired during early pregnancy. But I am beyond tired! All I want to do is sleep, at times I have to take a break at work "I drive a lot for my job" because I can feel myself getting heavy eyed. I am taking a prescription prenatal vitamin and I am getting plenty of sleep at night. I am just wondering if I should be concerned or if there is something that I could add to my diet to alleviate the sleepiness.
