I've heard about this also, particularly with Red Bull. Mixing any energy drink with alcohol isn't a good idea. The name Red Bull keeps popping up with cause for concern. I think they should put a warning on it's effects with alcohol.
I was speaking with a doctor earlier this week, that had commented that he is seeing younger patients having severe panic attacks after drinking Red Bull (energy drink) mixed with alcohol preferably vodka. It seems to be a clubbing thing to do especially in the West Coast. They stated they would mix it or drink it after drinking to sober up. I know most of us here don't drink, or even use energy drinks. But we have alot of younger teenagers here, or are parents of some, please speak to your friends and children about this, as they are starting to research this particular energy drink and the effects it is causing.
