Haha! I am still awake. After isolating the problem as lethargy, I now know what to do with it.
For the past few hours, I was quite depressed. I was bored, which is never a good sign. My mind was not doing anything. There were no puzzles to solve. I felt like doing really bad things to people all day long. Didn't allow that to get in my way. Everything's done. Everything's fine.
I guess, it's time to step things up a little. On all fronts. With the extra responsibilities, this is indeed beginning to feel like old times.
I need 10-12 hours of sleep, at least. And then, it begins.
