I'm not sure what the "blackout" part is...
The caffeine wakes you up. Most people I know (and I've know quite a few lol ) who blacked out did so from the alcohol. I drink Jaegar Bombs all the time (redbull and jaegar) and never "blacked out".
If anything they would be wide awake and drunk...and not even all that drunk since they would be sped up from the caffeine which counteracts the "downer" of the alcohol (the very reason people have used coffee and sodas to sober up for forever)
I know that if I fuck up and drink a little too much too early I always stop ordering alcohol and switch to coca-cola for a while to get some caffeine in me and to sober up a bit.
But I guess these bureaucrats in D.C. MUST have control over everything we do in our lives.
