For the last month I have been just as unproductive as the month before. The primary cause of this is an ailment that has been dragging me down since September: an intermittent drowsiness that robs me of energy. My doctor recommended changes in my diet, but those changes have not fixed the problem. I am now taking detailed data and will be reporting back to the doctor.
In the meantime, however, the enforced off time has permitted me to cogitate deeply about the issues.
