How do you organise your week after a layoff? - what worked for you?

I want a realistic schedule for the week that does not burn me out. I have read a lot of threads here and could not find my exact situation. 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.

A walk before I start and a call with a friend at lunch keep me steady.
