I don't think it's reccomended, but I allow myelf at least one peice of candy or sweets that I enjoy every day, so long as it is only one, and it has to be less than 4 grams per day. My only craving was the first week, now it's more of a reward for maintaining discipline. Last week, I found myself wanting the candy only one time, so it may be one of those issues where time heals the wounds
Good luck!
