I log sleep as well. My "lifestyle" is seated, some movement because that's how I am at home. However, my job is pretty active, so I log it as an activity. Maybe you should make your lifestyle more active and log the sedentary work hours? I find I burn almost 1000 calories more on a workday than I do at home (10 hrs on my feet, and a good portion of that spent restraining dogs).
If I keep starting over, eventually it will stick, right?
