Scale said "Error"

I hit this week running strong (after a slightly off course weekend). Monday, Tuesday and Wednesday (morning) I was the bomb. Meeting my first 5 pound weight loss goal... something happened Wednesday after school, it all started with the Wendy's drive through, then ended at Maverick having soft serve ice cream, what the heck? Wednesday I didn't even look twice at the treadmill, not good! Thursday, I ate school lunch, which I swore I wasn't going to do, then I ate out again for dinner, I'm at work, again, which I know isn't and excuse. I did get on the death machine today though, and it was awful! .. So I'm afraid to weigh in! Scale will probably read "Err"
