feeling lethargic

Lately I have been feeling quite lethargic even though I am eating clean, exercising and getting enough sleep. I am at home with my three young children for the summer. They keep me busy, but I am not sure if I am tired because they are active or because of another reason.

I am also taking a multivitamin, maca supplement, and calcium. I drink plenty of water, but I could be drinking more.

I did recently have my blood tested for basically everything and I am in excellent health.

Is it possible that it is psychological or is there something that I could be doing?

I eat every two hours. I am wondering if it is diet related. I wonder if I need more carbs. I think I eat enough carbs but maybe not.

Any suggestions or thoughts? Anyone in the same boat?
I'd love to hear some input.
Thanks,
Limaca

so I take it your iron levels are fine. Generally when I am feeling that way, my blood test results say that I am anemic
