so if you can have cheese as a snack, how come you can only have cream in your coffee once?

I went to the bookstore and got the "30 day carb addicts menu plan" and now i'm even more confused. For snacks there are nuts listed, there are fruit at 2 out of 3 meals, and here I was thinking the carbs are supose to be saved for the reward meal. Ugh...confusing.
