“You may need to have difficult conversations with your partner about what you need to get a good night's sleep. This may include sleeping in different rooms if snoring or tossing and turning is waking you up. It may also include agreements not to argue or discuss difficult topics before bedtime. You should also talk about sex and try to agree on what time of day is best for both of you to get more sleep—this doesn’t sound that romantic but for a healthy, stable relationship, it’s incredibly important.”
