i agree!!! I admit that i did drink alcohol in a moderation and lot fo foods, all day then at night, i switched to coffee for three hours or so. If i feel fine, then i can drive home. If coffee is not working then i stay over.
its be like Red Bulls +Jagermeister, the Jag Bomb = drunk and awake....LOL!!
that's if they didnt alter chemically to retain the caffeine, or added more caffeine like they do in Red Bull....
