Vodka and cappuccino?!
Answers:
This is similar to Four Loko. Recently, Four Loko was forced to change their recipe, taking the caffeine out of it because it caused many hospital visits and many even deaths. Vodka is a depressant and the cappuccino is a stimulant, so it is making your heartbeat go crazy basically.
As long as you keep it in control, you'll be fine. But be careful!
kind of like mixing red bull and vodka, they have opposite effects. so long as you didn't drink too much i think it'd be fine.
Not any more dangerous than drinking them separately.
Why don't you try it yourself and find out!
