When your schedules don't sync

• Use phone alarms with vibration, not a shared room alarm. Whoever wakes first leaves the other in peace.
• Two duvets, one bed. Solves temperature wars and the 'someone is stealing the covers' problem.
• Wind-down 30 minutes before the earlier bedtime. Whoever's still up should do it in another room.
• Weekends shifted more than 90 minutes from weekdays gives you social jet lag. Bring the schedules closer on weekends, not further apart.
