I'm just a couple of weeks out, and I experienced that so much the first week. I was so disappointed becuase I wanted my hunger/cravings to go away. But, once I started on some full liquids like applesauce, and some mushy food, I haven't felt much hunger. It only takes a couple of bites of those things and I feel so full and don't want food! The first week on Clear Liquids, no matter how much liquid you get down there is just not enough substance to it to make you feel full, but that will change soon.
