Why Can't I pass a McDonalds?

I have discovered that McDonalds has a magical hold over me. Whenever I go out I convince myself just to go through the Drive Thru and get a refreshing beverage for myself and kiddy cones for the kids. I tell myself that it doesn't matter if I only take a few sips since they are free (my mother in law gave me gift cards for mcdonalds for Christmas). My kids love the free Kiddie Cones and I love the distraction.

Now it is true that I love refreshing beverages but I have about 12 pounds to lose. I'm not giving up all refreshing beverages but I think buying two a day is adequate. Then I drink about 64 ounces of water a day. Needless to say I have to go to the bathroom A LOT......
