I'll get straight to the subject of the title: I woke up from my 3-hour core sleep tonight before my alarm went off. It's after 5 am, and I've now been up for over 2 hours without feeling sleepy enough to go back to bed. I even tested it by reclining on my bed for a while, and I didn't feel at all in danger of dozing off. This feels like I've made a genuine breakthrough in adapting. It's a little exciting.
Now, I'll go back over the days since my previous update:
On the night of the 25th, I slept my core from midnight to 3, as has inadvertently become my habit. For some reason, it still feels "early" to go to bed before midnight. I woke up at 3 feeling good, but also yawning and sleepy. I had to be out at my usual naptime around noon -- and I was feeling a bit tired then. I tried to doze in the car while someone else drove, and I got a little rested from this, but it wasn't adequate. I finally got a chance to nap at 15:00, and I decided at this time to just lay down and see how long I naturally slept, as I was really exhausted and figured I might need some extra sleep to make up for the lateness of the nap. I slept for almost exactly 3 hours, and woke up just after sunset feeling a little surprised that I woke up in the dark and was wide awake. I always find it a little eerie to wake up at that time, because it feels like waking up at dawn, except the light is vanishing.
That night, I had a little trouble falling asleep, and finally dozed off close to 1:00. I woke up at about 2:20, about 80-90 minutes later. I felt okay and was tempted to get up, but I decided to go finish the core sleep, as I'd set my alarm for 3 hours at 00:30. So, I woke up with the alarm at 3:30. Felt the same as the night before, sleepy but not exactly tired. I sat in an armless chair to relax and work without danger of getting too comfortable and dozing. I stayed busy all morning and then took my nap at 11:30. I was very tired by then, but I had a hard time sleeping and felt a little anxious about getting enough rest. I woke up at 12:30 on my own, after a few short dozes. I was tired but also felt decent. I went to bed earlier that night, and set my alarm for 2:30, as I was still wanting to move my core sleep back from 23:00 - 2:00. Anyway, when I woke up at 2:30, I was okay but still rather tired. I decided to take my morning nap early, and I had a hard time getting up from it. I slept 90 minutes, woke up exhausted, and slept 90 minutes again to try to feel better. I don't know if it was an accumulation of fatigue, or the fact that I took the first nap during my sleepiest hours, but I didn't really get rested. I felt better later in the day.
Last night, I felt a little tired around 23:30 and decided to run with that. I went to bed and set my alarm for 3, as that seemed to be working for me, and laid down and tried to go straight to sleep rather than laying in bed and reading until I'm ready to fall asleep, like I usually do -- it's difficult for me to get sleepy at that hour unless I'm just exhausted. I fell asleep before midnight, and then woke up at about 2:50, without the alarm, and feeling good. I got up feeling enthusiastic about waking up naturally, and have not felt like dozing off at all.
It's really a different feeling than I've had the last several days. I feel like maybe, *maybe* I've gotten over the morning sleepiness. I'm going to do my best to get in a good 90 minute nap before noon, and hope that keeps me going strong like this.
