Christmas Rehab

That time after New Years after you've put on 15 or 20 pounds from the holidays in which you plan to lose a large amount of weight, but only get around to losing at most half of that.

John: Well, now that the holidays are over, its time to check into Christmas Rehab.
Liz: Last year I didn't even make it to half of my planned weight, it took me all summer to work it off.
