What kind of crap was it? Maybe we can help you with some recipes.
Like everyone has said, forgive yourself and move on. If you think you are acting like a food addict, maybe try to find the underlying cause. What is triggering you? What did you say to reason yourself into it? And, maybe if you feel you deserve something ("just this once...I have to have it...") go and reward/distract yourself with a non-food item.
If it is all just too much to handle, try going to bed early. These are just cravings, they will pass--but you have to be stronger than they are. If you aren't, then this will all be a big waste of money. All I can say is that if you are faithful to the plan it is 100% guaranteed to work! Seriously! No guessing, no wondering, no worrying. So, be happy that you found IP and commit yourself to following it. It's not that bad--I mean, there are diets out there that have you eating cereal for 2 meals, or only salads, etc. How unsatisfying! At least we have some degree of normalcy on IP and with a little preparation and creativity, you can actually enjoy yourself.
We are all here to help, but no one can carry you--you must carry your own weight and if you stick to the plan, that weight will be easier to carry!
