When you get to the "Just one more turn" mentality about your own soul. You need an extended break.
Back in Finland. During the winter war. When the lines were about to collapse and the situation was most critical and everyone was freaking out. Mannerheim (The Finnish war-leader at that time) simply ordered everyone (edit: Everyone making decisions/command officers) to have a full nights rest.
The conflict would not be decided in the next 8 hours but decisions made under bad influence or while tired during the next 8 hours could cost everyone the conflict.
Hope that anecdote helps.
