This may be a moot or fickle point and not so much for just yourself but also others that are planning.. If your working from home there would be less temptation. However, if you are going to work somewhere where do (and to each their own) vending machines at work, coworkers putting together a take out list of fast food to be brought back for lunch, tobaccoo, coffee/soda figure in? Not a biggie in a week scenario, but a year would be a stretch for some.
