Can drinking red bull before going to bed affect sleep?

Red bull contains caffeine that excites the central nervous system. According to the principle of equivalent calculation, a cup of red bull is equivalent to four cups of coffee, so drinking red bull at night may make it difficult for people to sleep, even sleepless all night. Therefore, it is recommended to avoid drinking red bull two hours before going to bed. If you have already drunk it, you can dilute the drug concentration, promote excretion and relieve it by drinking water properly and exercising properly.
