I think my natural cycle may leave me unproductive in the afternoon. I'm sure the lethargy I'm feeling right now has at least something to do with having recently eaten, but I think it might also be just the time of day. Before Thanksgiving, I was getting in to work by 6:30 at the latest, which, with a 7 hour work day and a 1/2 hour Boggle lunch, let me get out of there by 2, which was just about perfect. I would drink soy milk for breakfast once I got to work, and then a can of tuna around 10:30, and then eat and sleep after I got home from work around 2:30. I think I may have to try to get back onto a schedule like that, since it seems to fit the way my body works better.
