Related to Listerine: I have a memory of reading a study that had people use mouthwash (possibly Listerine) the night before taking a cognitive test. The mouthwash group did worse than the control group for some reason.
I'd really love to find the study again if anyone else knows where it is (my googling is apparently not good enough)
