ELI5: Redbull & Alcohol. What is happening to our brains when we combine them?

Google seems to turn up conflicting information. Red Bull's website says there is no scientifically proven effect while some articles seem to suggest the effect is similar to cocaine.

EDIT: I hope this flair is appropriate/correct.

Alcohol is a depressant in that it slows down the central nervous system. When you're drunk you lose balance, become more emotional or angry and violent, and become tired. Red Bull has caffeine which is a stimulant in that it increases central nervous activity. However, when you take both at the same time, the alcohol will still depress your central nervous system while the caffeine in Red Bull will make you feel as if you're sober and alert. The key word here is feel because the alcohol will still affect your reaction time, balance, and emotions. The danger of drinking alcohol and Red Bull is that you could feel sober causing you to drink more alcohol and/or doing something that you shouldn't be doing while intoxicated.
