If a 15-minute nap during the day = 90 minutes during the night...

[Pheesh]

I never understood this power nap thing. I nap for thirty minutes, I wake up going, "Crap, two more hours please?" I feel like death, and sometimes even get nap headaches.

This, basically.

The only time I can sleep during the day is if I'm sick or if I've been up for 24 hours+
