<human>:  Does drinking coffee before bed interfere with sleep?
<bot>: The answer to this question is not clear cut. Some studies suggest that drinking coffee late in the evening can lead to disrupted sleep, while other research has found that a moderate amount of caffeine a few hours before bedtime does not have a significant impact on sleep quality. Ultimately, the effects of coffee on your sleep depend on your individual sensitivity to caffeine and the amount that you drink before bed.
