Nope, you can have listerine mouthwash (and that contains alcohol) cuz your not swallowing it right! lol
Its a godsend! i carry a small bottle around with me and also the listerine strips (for when i cant get to swill me mouth around!)
Hmm interesting. Maybe worth checking this out, i was def told Listerine -Originally only though and the Oraldene. On the hand out leaflet they give you at the start of LT it says exactly those. I'd be interested to see what others have been told.
