I have fallen lots of time especially in the beggining while stopping/slowing. But in my defense I started out riding my bike with clipless. So I had to learn my bike, balance and timing along with unclipping at a red light or a stop sign. I think that you are going to be fine. Rule of thumb, if you think that you are going to stop unclip one of your shoes. It is easier to clip back in than to pick yourself up off the road.
