Fatigue and length of play time

[BEEK]

I was wondering how long the better non-tournament players play in a session/day/week?

How they deal with fatigue issues?

How they know when they are becoming fatigued? What then, coffee? Call it a night altogether?

I realize that the better the session, the longer one stays in and fatigue is minimized. I am speaking on average, day in day out.
