Lack of Self Control

In just few days I ate a dozen of Krispy Creme donuts (a big thanks to Ana Marie who brought the said donuts from London). It was so yummy that I cannot stop eating. Thinking of it now make me guilty because I want to lose some weight. But what can I do? Right now I am lacking of self control, that every time I think about dieting, it makes me eat more. I think I need to do a colon cleanse to detoxify me or else I will make myself more fat.
