The LBS that sold me my bike two years ago, with clip-in pedals, made me promise faithfully to take it to a quiet park and clip each foot in and out 10 times before i tried riding. I did, and I haven't fallen (yet?). Another tip is to make sure you can clip out with either foot if you need to. I always take my right foot out when I stop, and had to change track pdq when my laces got caught in the right pedal, and I had to unclip with the left. It worked, but was something of a wake-up call. Enjoy.
