Question for B&M pros

[Paulie Walnuts]

Something I was seriously wondering earlier while lying down for a nap. When you make the trip everyday to play poker how many buy-ins do you bring to the poker room? This is a serious dillemma for me. I would love to hear advice and strategy for different amounts. I am mostly talking about NL holdem here but another question would be how many big bets to bring if playing limit holdem.
