Hi everyone - I need some advice. I'm on day 3 and I am still starving. I mean tummy-rumbling emptiness. I have had my shakes, black coffee, and averaged about 2 liters of plain water a day in addition to the water in the shakes and coffee. The only other things that have crossed my lips are splenda tablets in my coffee, toothpaste and listerene strips for the pongy breath. What am I doing wrong?
