Going West (from Europe to the US for example) I wake up really early the next morning, then one hour later each subsequent morning. Takes about a week for a 7-hour time difference.
Going east is different. First morning after I am up around 7 or 8, second day I can sleep until 1 PM if allowed to. Then it alternates the following days like that, for about a week for 7 hours as well.
Seems there is some kind of 25-hour cycle active on stretching the day, and a 48-hour cycle in action on compressing the day.
Shorter differences, 1 hour or 3 hour are similar, but the transition time is correspondingly shorter.
