I had my first gain this week ... It was only 4/10 of a lb , but man was that a blow . I knew after We d that this weigh in would not be pretty , but I'm proud of myself because I held myself accountable and now I'm determined to get back on track . We went to my company's Christmas party this week and I overindulged . I also ate Krispy Kreme at work yesterday morning . 
Question: What was a blow to the writer ?
