Thanks for posting. I read this:<p><i>For example, DSPS students often get a short sleep in the night, wake up early with an alarm clock, go to school where they are semi-conscious and perform poorly, get a solid nap after school and only late in the evening they regain vigor and their full mental powers. DSPS students feel best after midnight when everyone else is asleep and they can focus on learning or other activities (reading, Internet, watching TV, computer games, etc.).</i><p>And thought, "this article is about me".<p>In an effort to understand my own sleep patterns, I bought a Zeo. After a week or so, I think I've found how things work. If I get a lot of deep sleep, I may not "feel awake" or refreshed, but I can think really well. If I get a lot of REM sleep, I feel great, but may not be in the mood to do anything. With that in mind, I am trying to figure out how to get a good amount of both in the same sleeping session.<p>I haven't had a chance to try this yet, but my plan is to tire myself out (hopefully corresponding to nighttime, just to be in sync with the real world), get a lot of deep sleep, and then when I wake up, check that I've gotten enough REM sleep. If not, back to bed until I feel satisfied. (I am pretty good at getting REM sleep in the morning. Alarm goes off, alarm set for +1:30, and I get about 1:15 worth of REM sleep. Great dreams in this period too. It helps that my work schedule boils down to "try and show up before 2" :)<p>Anyway, I guess I don't have enough data to say anything conclusive, but this is my plan.
