Look people this WOE (way of eating) is not forgiving.
If you slip, if you cheat, then you will not lose weight. It is very simple.
It is hard.
You have to plan to have food around you that you can eat and (very important) that you like to eat, and - if possible - stop buying the dangerous stuff that will tempt you.
It's also really important that you take a long, hard look at why you turn to foods that you know will sabotage your efforts. Just because you're dieting isn't going to stop the hard days, or the stressful dealings with the DC. You have to find different strategies for coping with these, otherwise you will just end up undoing any good work that the low carbing is doing.
Worse, if you start combining these 'treats' with a low carb diet, what you are actually doing is eating a high fat and high carbohydrate diet - which will mean that you gain weight.
Seriously people.
I know that this is a support thread, and this post probably doesn't sound very supportive! 
But stop it!!!
