On board Exit Only our watch system is a non-system.
I stay awake until I can't stay awake any longer, and then I get someone else up. Because I am so tired, I instantly fall asleep when the next person comes on watch.
My secret weapon is DVDs. When I get my wife up in the middle of the night, she can easily take watch for 3 to 5 hours as long as there is a DVD
running in her portable DVD
player. It's totally magic. Every ten minutes she checks the horizon, and the DVD keeps her wide awake. If she should get tired, she gets me up or someone else up so that she can instantly fall asleep when she hits the bunk.
Nobody lays awake in their bunk counting the minutes before the start of their watch.
It's kind of a weird way to run a watch non-system, but it works extremely well on Exit Only. I end up taking more hours of watch than the others, but that doesn't matter because I still get my sleep, and I never lay awake in a bunk thinking about going on watch.
