I take power naps everyday for 10-15 minutes. I use to go home after work so tired I would have double vision when I drove home. With power naps, I am alert. I also use an eye massager for 3 minutes. You can find them on the internet. I wake up at 430AM and take a nap at 730 when I get to work. I also take one before I leave at 300PM. Naps are a life saver for me.
