When do you get up?

[knght311]

I 8 table 2-4 LHE on FT and always have concerns as to when to get up....for instance, last night I played about 100 hands and won 111 dollars. I stopped and took the rest of the night off.

And tonight I played 1.4K hands and after hovering about 16BB down I managed to crank it up and win about 7BB and stopped.

When do you guys stop?
