i would say lay off all of the artificial sweeteners. some people have a big problem with them, as far as losing weight is concerned. losing weight when you're 13 is a lot different than losing weight at 41. i would say give up the all of the sweeteners and try to make yourself drink more water for a few weeks and see if anything changes. if not, you can always go back to drinking the sodas. also make sure you check the carb and sugar content of the salad dressing you use. i've never used it so i don't know if it's ok or not.
