I thought that I wouldn't be hungry after getting rid of so many carbs?

Does it take awhile to get to that point? I eat b'fast around 6:30am, then need a snack around 10, lunch about noon, then I'm hungry again by 2:30/3...I can't go to bed w/o a snack either.

All of my snacks are LC (cheese, cucumbers, mushrooms, etc.). I'm drinking about 120-150oz. of water. Does that have anything to do with being hungry?
