After getting five hours of sleep per 50+ awake, I have engaged "Recharge Mode".
Recharge Mode is waking up, looking at the clock, and deciding to go back to sleep.
Rolled into the office at almost 11:00am this morning.and have spent the day, thus far, perusing developer blogs and mailing lists. Code editor is open but ignored.
NOTE: Even in Recharge Mode I am working. There's always a thread in my brain dedicated to projects. I just assign it a very low priority.
