Digital Jet-Lag

When communicating with someone digitally in a distant time zone by phone, text, video chat or Skype, digital jet-lag is the feeling of being tired or fatigued from said communication and its disruption of your normal schedule and routine.

Joey: Why are you so tired? It's only 5pm where you live.
Damon: I have digital jet-lag from staying up until 3:30am video-chatting with you.
