When I 24 tabled I did two separate sessions and tried to make them at least 3 hours. That's about the point when my brain started going numb. There's basically no way you're going to make it to the bathroom and back without missing a hand on some table, and depending on how you lay things out it might be a nuisance to go find that table. So, try to make sure you go beforehand.
I usually ordered delivery or had snacks around although I really probably shouldn't have since it distracted me.
Sometimes I would end sessions early if I was getting owned, it was really just making sure I was still in a focused state of mind.
