I work out of town 35-40 weeks per year. On those weeks I'll go to bed at ~2AM. I get most of my admin/computer work done between 10PM-2AM and spend all day in the field working from a truck. It's the weeks I stay at home that get me screwed up. I'm been staying up until 4-5AM all this past week and just sleeping until my phone rings, usually 8:30-9AM.
I’m an early riser, always have been. But I can also stay up pretty late at times.
Today I happened to be going from just 4 hours of sleep. Last time I looked at the time last night, it was just after midnight. Been up since 4am this morning. This isn’t typical, just happened to be what happened today.
