Cravings for desert

Whenever I eat food, ( I eat 6-7 small meals a day) I get cravings for desert as soon as I finish my food for like another hour or couple of hours. I generally dont buy desert and keep myself away from sugar. But sometimes it just get unbearable and at that time I dont even want to think of weight loss. Now I have stopped keeping any money or credit cards with me. Or else I would go and buy it from cafeteria. Is there any solution for these cravings? anyone else in same boat? I generally crave for chocolate, cake, ice cream, pies, etc. If I eat a piece of it then I want more of it and believe me I will go and get it and then feel guilty all day and night about it. Any other suggestion of low calorie deserts or soemthing like that?
