A friend should understand. The one exception is a very special ocassion such as a wedding. Take time for a power nap (set an alarm so you sleep less than 30 minutes)? Red bull?

I wake up between 1 AM and 5 AM. When I walk my dog at 3 AM, etc, I feel like I am the only person in my whole neighborhood that is awake. I have been doing this since a very young age. I just look at it as quiet time with no obligations!
