sleep-wise when I'm alone, I try to get my head down for 25 minutes at a shot for most of the night. If I can do 90 minutes nonstop once during the night, that means I'll get into REM sleep, and come out of it, once, naturally. I try to do this between midnight and 3:00 AM. 90 minutes without an AIS is kind of scary, as it takes about 20 minutes between when a container ship appears on the horizon, and when it goes SMASH into your boat, so anything over 20-25 minutes is a risk. However, being stupid is also a risk, so I take that chance.
