CheckWithYourDoctor: Assuming you're of average size with no liver or kidney problems, not on medications that make you drowsy, or take any downers or drink a lot, or intend on driving or operating heavy machinery or have to study for a test or go to a movie intending not to fall asleep half through it or are going scuba diving you should do OK. But,really one of them is probably enough. Check with your doc;
