I want to correct an erroneous assumption I'd made in the past. I believe I've said in this blog something that I've often heard others say and that I'd previously thought true: sometimes it's hard to fall asleep because my mind just won't be quiet. I've determined that, although laying in bed with my thoughts racing is related to not sleeping, the unquiet mind does not cause the lack of sleep. Rather, it is being in bed, in a quiet, dark room, and unable to sleep, that causes my mind to wander like that. Sometimes being in this state will make me suddenly feel more awake as I think of something that I want to do when I get up, and I anticipate doing that. However, this is caused by and not the cause of sleeplessness. Because, truthfully, when I am really, really tired and sleepy, no amount of racing thoughts or desires to do something will keep me awake while I'm lying in bed. No matter how burning that desire is to just read a little more, or whatever I'm doing, when I'm genuinely sleepy, I can't do it.
I'd previously mentioned maybe taking a short, 20-30 minute nap this time of day on days when I'm tired, but I was unable to do it today. I am feeling rather fatigued, although I don't know if that's due to polyphasic adaptation or due to my workload/spending too much time busy. For me, being fatigued does not equate to being sleepy. I'm not sleepy, so I am unable to nap. Other than the fatigue today, though, I feel that I'm doing fine with my adaptation. I hope to get some good sleep during my core tonight and maybe get rested up. I had no problem waking up from the core this morning, but found myself dozing a little while I sat in bed. As I enter what should be the harder part of the adaptation, I need to be vigilant against that, and make myself get up and work on the computer at that time. The artificial light helps one stay awake. I'll reserve reading for daylight hours if I find myself getting too tired at night.
I'm not sure how long to test a sleep pattern before determining its efficacy. I'm going to say that 2-3 weeks should be a decent test. If after 3 weeks I am fatigued and sleepy for long periods before or after naps, this is probably a sign that it's not working. So I will try to pay close attention to my energy levels for the next couple of weeks and see if there's any improvement.
