One easy way to keep your clock on track is to wake up at the same time each day. If you can maintain a consistent waking range every day of the week, you are less likely to shift your circadian clock and get out of sync. Maintaining a constant wake-up time will also lead to a stable bedtime. At a minimum, do your best to keep wide time shifts from occurring, even when you travel. While sleeping in on a Sunday always sounds good, the reality is, you pay for it later.
