We all have things that we still enjoy as a treat! I have my Cincoshakes from our local "starbuck-like-but-better" shop.. I now order it with 2% milk and no whip cream. It comes out to about 8pts. I only get it about once a week, if I have extra room, if that!
You could also find a way to make that a bit healthier at home.. potatoes, low-fat cheese, lf or ff sour cream.. I bet it would still taste just as good!
