Human: Is it true that if you drink a glass of water before you go to bed it will help you fall asleep faster? Assistant: 
Yes, it is true that drinking a glass of water before going to bed can help you sleep better. Drinking a glass of water can help reduce the amount of caffeine and other stimulants in your body which may help improve your sleep quality. Additionally, having a full stomach can make it harder to get comfortable enough to fall asleep, so hydrating before bed could be beneficial for helping you get better sleep.
