That is possible, but I currently suspect the circumstances more than the time. I'm essentially alone (my wife is sleeping), and I'm not distracted. (Because I'm in bed and not on a computer with an internet connection) The circumstances might also explain why the ideas are generally low quality (because there is no one to bounce them off for obvious flaws, and because I'm tired although I don't realize it.)

My life currently has little scheduling freedom in general, but I do have a vacation time set between Chistmas and New years which I am taking at home, so I can continue noting any sleep disruptions with more ability to be flexible. A chance to take a break of caffeine and to have the freedom to nap if desired both sound good at this point.
