Sorry to hear you guys had regrets :(.
I never did, and really I am not hungry per se, just miss the taste of certain things. I'd love to eat a salad, for example, or some steak. Not really craving anything other that real food that isn't mush.
I totally get the concept of food curing bad days, it did that for me a lot, but the feeling I have even losing a little weight has made me feel so much better. I am trying to find other more healthy things to fill that void.
