I have had my morning shake at 6:30, and no I'm not hungry, but I would really like to eat right now. Why? A bit of boredom, a bit of panic when I realize that I won't eat again until 11:30 (3 hours), missing pleasure that comes from the act of eating.
Of all the things in my life, I think that overcoming the baggage that food has will be the hardest. Not impossible by any means, but hard.
