Current Schedule: Core Sleep: 10pm-3am Naps: 6:00-6:20am, 11:20-11:40am, 5:40-6pm.
Finally, I think I got three good naps today. Unfortunately, they weren't at the right times - my second and third naps had a pretty big offset. Nonetheless, I seem to recall going under and waking up at least somewhat refreshed after each one, which is pretty big progress for me. The question that remains to be seen now is whether I can do this repeatedly, or if this was just a fluke.
