Alternatively, do this to get yourself ready to sleep tonight and start fresh tomorrow:
Start by identifying an exact time when you want to be in bed. Be specific. Trying to go to bed “as early as possible” is hard to achieve because it doesn’t give you a clear idea of what success looks like. Instead, think about when you need to get up in the morning and work backwards. Try to give yourself 8 hours, meaning that if you’d like to be up by 6:45am, aim to be under the covers no later than 10:45pm.
Next, do a nighttime audit of how you spend your time after work. For one or two evenings, don’t try to change anything—simply log everything that happens from the moment you arrive home until you go to bed. What you may discover is that instead of eliminating activities that you enjoy and are keeping you up late (say, watching television between 10:30 and 11:00), you can start doing them earlier by cutting back on something unproductive that’s eating up your time earlier on (like mindlessly scanning Facebook between 8:30 and 9:00).
Once you’ve established a specific bedtime goal and found ways of rooting out time-sinks, turn your attention to creating a pre-sleep ritual that helps you relax and look forward to going to bed.
