You didn't really cheat (I hate that word! LOL!), you made a bad decision that day. I don't think one day makes you have to start over. If you find Atkins too restrictive or hard to keep up with, try another low carb plan. As Kristine mentioned, there are others that allow more carbs at the beginning. With only 10 pounds to lose it may take a little while, so it is important that you don't get too discouraged. It will be easier if you find a plan that you really like and can incorporate into your life. Remember that you are doing this for your long term health.
