Went on a sugar binge today. How much will I gain tomorrow?

After almost a month of counting calories and eating well, I binged again. I feel sick to my stomach and the guilt is overwhelming! I think I ate 3500-4000 calories today. I ate a lot of chocolate, honey and nuts. I don't think I ate this much sugar in a long time. How much should I expect to gain tomorrow? And how do I get rid of the guilt?
