Ordering soft drinks when you eat out can add a lot to your waistline and the bottom line of your check. A family of four could save as much as $8.00 per check if they ordered water with lemon in place of soft drinks. If you do have soft drinks at restaurants, consider ordering the smallest size and skipping the refills. Ask for water also so you'll be less likely to accept the offer of a refill on the soft drink. You could easily end up with close to 800 calories of soda if you have refills of a large drink.
