Changing around my schedule

Since the start of this experiment, I have been able to set my own schedule. I work for myself and setting up meetings with clients is pretty flexible. Lately though, I have been the general contractor on a small remodel, which means that, not only am I working at the jobsite, I am working a number of subcontractors, and making sure that the they have the materials that they need, and that everything is staying on schedule. I was having a problem with my afternoon nap. I can't nap at the jobsite (partly because there is no place that is out-of the way and comfortable, but mostly because there is a perception that people who nap are lazy, and I will have a hard time getting the contractors to take me seriously.)

The phrase "Sleeping on the job" 

does not inspire confidence.

My schedule was getting up at 6am, napping from 1:30 to 3:00pm. The problem with this schedule was trying to match it to my subcontractors. They would arrive at 8, take lunch at noon, and then work from 1 till 4. If I am going to sleep at 1:30, then I need to leave the site at 1:00, and do not get back to the site until they are in the process of cleaning up. Additionally, I was trying to eat with them at noon, so my total work day would have only been 4 hours. For a couple days, I simply switched to monophasic sleeping, because it was easier. Now I am trying a new schedule. I get to the jobsite at 7:00, work solid until 12:30, nap for 45 minutes, return at 1:30 and work till 4:00 and then take another 45 min nap.
