GTD's great for making use of snippets of time which come about due to this topsy turvy-ness. When I was on night-shift I would usually wake up in the middle of the nights when I was not working unable to sleep. All I needed to do was look at my "computer" or "net" next actions, get on the computer and make good use of this time, rather than waste it awake in bed.
