When do you guys get up from a LIVE cash game?

[Papi Shasho]

The few times I've gone to the casino to play cash games, I sit in a 1/2 NL table, and sit with $100. I get it up to about $150, but I keep playing and eventually lose it to set over set or something similar.

Do you guys have a specific way of knowing when you should get up? I feel like I stay too long, but I feel like if I don't at least double up, I haven't done much. Is 1.5x your buyin a decent session?

I know they say you shouldn't get up until you feel you're not playing optimal poker, but would you guys get up after you get up to something like 1.5x your buyin? Do you get up, keep the profit, and sit at another table with $100 again?

I never feel like I did anything when I'm up to 150 or so, but then I think about it, and $50 after an hour or so doesn't seem bad.
