What kind of drinks are you drinking, may I ask?? If you want to lose a lot of weight fast, it will be water weight, like rivermom said. If you want that gratification, drink ONLY WATER this week. It will flush the sodium out of your body that is causing you to retain water. You will lose a lot of weight that way. At least then you will know how much is water weight. Then you will have the peace of mind knowing that all the rest of the weight you lose will be actual fat! That is a nice feeling, you know?
Keep on doing what you are doing. It takes 2 weeks for your tastes to change. So, stick with your good eating habits and after 2 weeks you will find that your cravings will begin to change. Keep up the good work!
