I'm supposed to be on a diet_comma_ but I couldn't help myself and I ate three chocolate bars. it happens we have to reward ourselves sometimes. dark chocolate is actually good for you!  But I'm supposed to be on a diet! I can't lose weight if I have no self control :( hey it was just one day! you got this... work extra hard for the next 5 days!
