I came to a (probably crazy and completely sleep-deprived) realization at 3:58 AM: maybe I'm permanently stuck on the European timezone?!
Now, stay with me...I am a terrible sleeper. I fall asleep around 10:00 PM only to wake up thinking that it MUST be just minutes before my alarm goes off. I glance at the time only to realize that it's 11:30 PM. 😳
My day-to-day sleep tips may be helpful to others -- either while traveling or in general.
