Seriously?
Don't you get all grumpy and have headaches after you sleep during the day?
I cant do it because most of the time it will take me at least 2-3 hours to get back to my senses and start to get less grumpy... nah, i cant do it i tells ya, I JUST CANT!
I'd rather miss 3-4 hours sleep then catch up by doing siestas..
