Have you started a journal and posted your daily menus? That would help us to answer questions. We might be able to see something you are eating that is causing the problem.

Are you drinking a minimum of 64 oz of water a day, plus another 8 oz for every 25 pounds overweight you are?

Are you eating low carb bars? Are you conting the carbs in your coffee, tea, cream and sweetner? Are you eating any or a lot of sweet treats sweetened with artificial sweetners?
