You don't indicate what your current weight is or what your goal is. Sometimes our goal is too low for our body's needs. Often, when we are closer to our 'ideal' weight it is harder to loose.
There are some thoughts to consider:
* How quickly did you drop your calories? I found that when I dropped even only about 400 cal's daily, I got very light-headed, nauseous and suffered severe hunger PAINS. It would wake me often during the night. I had to go back up and then gradually work back down.
* What calories are you consuming? It may be that you are too low!
* What exercise are you doing? (Type and time)
* Do you use the SP Nutrition Tracker? I couldn't see because you don't have a SparkPage.
