OT: How long to get tired playing poker?

[lacky]

I try to get up and take a short break after every set (about every hour). If I'm playing ring games I stop after 2 hours. If I do that I can take 10 min to an hour off and be ready to play again. If I try to push on and play 3 to 4 hours straight I'm generally much more fried.

Try short sessions with breaks/naps. If I do have to play long sessions (on a mtt day it can run 12 hours straight or more) I only play 3 or 4 tables usually.
