I've known lots of people who get an insane amount of calories from booze. But they ate pretty lightly otherwise.   People need to understand this.  If you want to binge, cut back in other areas.  If you have pregnancy cravings, go ahead and eat it and cut back your calories elsewhere.  Meat-and-vegetable-based soups are good for this, as are eggs.  I drink lots of diet soda.  Fats drink lots of diet soda.  They do it for the halo effect, I do it to budget my calories for food I enjoy.
