I have the same problems. Atkins makes it easier because during the early phases, we are protected from appetite and we also virtually eliminate the physical cravings.

I have found that when the psychological needs strike, about the only thing that gets rid of them is to do something active. It seems that anything works; exercise, cleaning, yard work, going somewhere and walking around. A good conversation, or debate help too. The worst thing is to just sit there and do nothing.

Fortunately, if we are circumspect about it, we can have some small snacks, such as nuts, or a little cheese. The trick is not to let the cravings cause you to eat too much. So I generally abstain from them if the cause is psychological. I think determination to succeed is probably the most important cure.

When you feel like caving in, go look in the mirror. I do that too. It helps. I think even in the future when I reach my goal weight, I'll use that technique to keep from snacking then too.

Good Luck!
