How do you organise your week after a layoff? (update)

I have been out of work for 18 weeks and my days blur together. There are 5 people counting on me, so I am trying to be careful. I tried blocking out hours for applications but I lose steam by noon. How many hours do you really work on the search?

I aim for three focused hours, then stop. More than that and my applications got worse.

Write a short list the night before. Waking up with a plan is a relief.
