Daily structure while out of work - first time posting

I have been out of work for 12 weeks and my days blur together. Any experience at all would help. I tried blocking out hours for applications but I lose steam by noon. What helps you switch off?

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

Thanks for writing this out. I went through something close to it 3 months ago, and it got easier once I kept a simple log of every call and form.
