You need to find something to do during that time which makes you feel better about the fact that you are losing weight - exercise, or perhaps sewing clothes or even just picking them out online so you are preparing yourself for the changes you are going through.
Also, I drink a glass of water when I feel like that - it makes you feel less hungry and also concentrates your thinking somewhat.
Ha, COCK, glad to help! Thanks for the ideas. I don't know the first thing about sewing, but the water sounds doable. I've also heard a suggestion of brushing your teeth. Sigh. Maybe I need to break out the vibrator or something.
