Yeah, its definitely a marathon.
A big problem i have is that after so many hours of playing I start getting tired and then make a costly mistake. Just today i was up to 100k chips and lost and all in to a smaller stack and wound up with 40k - that was enough to bubble and I just missed the money by 4 places!
I think I'll take your suggestion and just go to sleep once I hit 100k! Bank the money while I still have it
