Find your routine
In a typical office, you are naturally forced into a routine. I need to wake up early, shower, and drive to the office in order to ensure that I am at my desk from "9-5".
Without a forced schedule a typical day can become much less regimented, and you can find yourself working odd–longer hours to overcompensate. That little voice in your head starts whispering, "Since you're saving commute time, shouldn't you be working more hours?" Ignore that voice. It's lying to you.
