- Buy a notebook and only use it for sleep diary and not a miscellaneous note pad.
- Be consistent and write every day. This can be difficult but it will be worthwhile in the long run.
- Write down anything that happened during the day that might have affected your sleep.
- Be truthful
- Be descriptive. Don’t just say ‘sleep was bad’ that really doesn’t tell anything.
- Ask your partner about how you slept. Was your snoring worse than usual? Did you toss and turn all night?
