I agree that cutting out the frankenfoods is a good idea -- it definitely stalls some people. You might also try switching over from diet coke to a soft drink that is sweetened with splenda instead of aspartame, such as Diet Rite. Or you might have to skip the diet drinks altogether.

Although I agree you should cut out the peanut butter bar and see if this helps, snacking can still be a healthy part of your diet. I eat three meals a day, and two snacks (1 in the afternoon, 1 in the evening after dinner). My new fave afternoon snack is cream cheese rolled in prosciutto (thin-shaved Italian ham). If you stick to just 2 T cream cheese spread out in 4 slices of prosciutto, your carb count is only 2g. Yummy!
