If your bankroll is staying the same, then you are actually ahead of the game (as the house takes a rake from every hand, so you are winning more than losing).
If you are playing a decent amount of time during the month and half, then make sure you are taking advantage of any promotion money the site is offering. Can you get a bonus with a deposit where the bonus is paid out as you rake hands. Even if the deposit is proceeded by an equal withdrawal, the software will often give you the reload bonus if the site is setup to offer this. Check out the web site of the site and see what you might be eligible for, often all it takes is for you to opt-in.
