Well, what does your diet look like, or at least the planned diet. How about a p/c/f breakdown, stats, etc.
I think people like to have weekley refeeds to keep their sanity, but then again, I've seen their diets and its pretty hardcore. I've only been on my cutting diet about 2 weeks now. I've had a "cheat meal" but, it was still relatively healthy, and the rest of the day was balanced out to make up for that. Recently I've been craving sugar, but, not enough to break my diet.
It all depends what you can go through. I get 30% carbs a day, so, refeeds are not necessary for me, I think. If you're on a more extreme diet, or if you feel like you're about to break the diet, have a refeed, but plan it.
I like to look through pics of people who are ripped in order to keep my determination. One of my friends, she used to post pics of models on the refrigerator in order to keep her determination when dieting. I'd do the same, but, putting up pics of guys just seems... wrong... and gay (not that there's anything wrong with that. *maintains political correctness*)
