I am suffering from a carb hang over

....I went to lunch with my cousin today and blew it. That monster was whispering sweet nothings in my ear and I listened.
Why do certain people trigger all of bad habits we are trying to get rid of? Stress,boredom,familiarity? What ever the reasons I always seem to dive head first into something I have sworn off when ever I am around her.I feel stupid and weak because I know better....Now I am up all night with a tummy ache and am kicking my self.One day will I slay that carb monster and shut him up for good !
